    Tire pressure (motorbike) safe?

    Tire pressure (motorbike) safe? 15th Sep 17 at 9:48 PM
    Hey all,

    First time posting on here! I just need some advice with regards to my motorbike.

    Basically, I have 2 weeks to drive it 10 miles and need to get it back in time to declare it SORN in a safe location. It is completely road legal until the 1st October

    I used it a short while back and when I got to my location (a friend's house 10 miles away) I noticed that the back tyre had become sort of flat... It pretty much happened on that journey.

    It feels flat when you ride it (the way an underflated bicycle tyre drags). I've only tried it around the car park.

    It feels fairly solid when you squeeze it on the stand, but the front one is much much harder (like a rock)

    It also has cracks around the side which I initially put down to vandalism, but it looks more like wear and tear damage. Not sure when those developed, but assuming it was during the ride up to my friend's house. Also assuming that this is the problem.


    Sadly, the nearest garage is probably 5 miles away (or more) and I'd probably be better just going for the 10 miles back home.

    My questions:

    1. Will pumping it up at a petrol station be a good idea? Could I get home on it?

    2. If its a good idea, how much do they cost?

    3. Could I potentially make it home on an under inflated tyre? If I did like 20-30 mph all the way? Does the contact potentially increase the risk of tyre blowing out?

    Cheers all! I'm a bit useless with motorbikes/tyres!

    You didn't read my post (which had lots of detail explaining why I am actually contemplating it) but thank you all the same for your input.

    You may be the safest driver there is, but you are contemplating riding your bike with defective tyres.

    You may be OK, you may not, who knows.

    You're only going to do 30ish so that's OK, unless you end up having a blow out and ending up under a HGV or something.

    Aye, but I admittedly do not have the knowledge about tyres! I didn't know whether it could blow out, or whether it would be safe enough to make it home (10miles), the garage (5miles) or even the nearest pump (0.5 miles). Or what other options were available. Or whether using some sort of glue (the neighbor offered me use of some, which is for a motorbike I must add) would be a temporary fix. If I had it my own way I'd go to the nearest garage (over the road). Sadly, this is closed down due to refurbishment for a few weeks

    Criticism is fine, but some people are making out like I was not going to listen to the criticism and drive anyway!

    So you guys have taught me not to do something which now seems quite silly to me

    I've only came of my bike once, at a slow speed 25-30mph, wearing full textile gear and it bloody well hurt, bruised ribs and knee which took about 2 weeks to feel better, big graze to my arm and my gloves were wrecked and visor of helmet scratched to f*** so new helmet needed.

    Good luck.
    Aye, Its brutal. My only crash was doing about 3-5 mph in Stratford. Hurt like hell.

    I've never had a flat tyre so don't know whether it is dangerous and, before doing something potentially dangerous, have asked for advice

    Nope I haven't read it, because I'd normally just take it to the garage/rely on the MOT for problems.

    I do, however, carry out routine checks every time which I learned on my CBT test (been called sad in the past for doing that!) and one of them includes checking the tyres before every ride.... Hence how I came to notice the problem in the first place. Initially thought it was vandalism because of the slashing, but it looked more cracked

    I probably should do that, but I am happy with the level of checking I carry out. It is much more than most people, and I drive safely, so I don't mind But even so, the tyres were fine when I set out and they weren't the day after when I went to leave.

    I want to be able to word this in a really polite way, but basically I don't care I drive safe, I look after the motorbike, I pay my tax/insurance, I have a full UK driving licence, I have current CBT tests, I follow the highway code, I regularly check the basics before a ride. That's enough for me! If it isn't enough for you then file a complaint with the universe

    If the bike is going to be SORNed for any length of time have you considered getting it moved by van/trailer to the location where you're going to store it? That way you will save having a brand new tyre sitting in storage and aging, then you can just get the tyre/s replaced when you recommissioned the bike.

    Even if you don't know someone with a van/trailer, I would assume that recovering a bike to a location 10 miles away would cost considerably less than a new tyre*



    *I have no idea what bike tyres actually cost, but given the way that several of my biker friends bang on about the cost of them I assume that they are in the same league as gold bullion or saffron.

    Sometimes seems like it, at c£120 rear and £80 front, and rears last about 4000 miles for me, front twice as long. Would never own a tyre long enough for it to age.

    Originally posted by Manxman in exile
    Why do you want to argue this?

    I checked tires before leaving. Fine.

    I drove 10 miles. Fine.

    I went to ride it a day later and noticed cracks on the side and it had gone down a bit. I initially thought someone had slashed them because it happened overnight and it was parked on a small housing estate in a fairly inconvenient place (the only place which allowed me to lock it up), but upon closer inspection it looked too *random* to be vandalism (ie it was more around the whole rim and was jagged, not straight).

    And you also seem to be asking how to keep the tires properly inflated. How have you dealt with this problem in the past?
    The tires have always been inflated when I've checked them, so I haven't "dealt with this problem in the past".

    The only things I've done are:

    1. Give it a yearly MOT and get it up to speed
    2. Replace the other tire (or maybe both, I can't remember to be honest) about a year ago due to loss of traction.
    3. Use it for maybe 2 miles commuting per day, 5 days a week (so light use really) in the past year, with the odd trip up to partner's place (10 miles).


    And you "don't care" so more responsible people should file a complaint with the universe(!).
    Ultimately, I don't care about whether you or the other person think I'm a safe driver. I follow the highway code, I perform basic checks and I ask questions when I'm unsure of what to do. Don't give a rats !!! beyond that I'm afraid, so if that isn't good enough for you then sorry! You will have to file a complaint to the universe!

    I would not have a problem if you rode the bike the 10 miles on the rim, I just wish you would stop using American spellings

    My only worry is I have little money and little time to get it fixed

    Good idea actually! Just hire a man with a van. I could declare it SORN at my current location and then transport it in the van. Cheers!

    I check the tires, and everything else (lights, mirrors, gauges, L plates etc), every time and in line with what I was taught on my CBT test.

    Much of that is just through observation and feeling it. Maybe I was taught wrong? But in fairness, I think proper bike maintenance comes with the qualifications which allow you to ride motorbikes higher than 125cc. People say "refer to your manual" but most laymen simply pay for a garage to make the repairs! That's life! That's what I wish I could do right now!

    I readily admit that there are things I could do to make it *more* safe, but I've been driving for many years now (car and motorbike) and I am happy with how safe I am. I sadly don't have as much knowledge on tires or motorbikes hence why I posted on here. Don't mind a bit of criticism like, but there are people out there who wouldn't think twice about doing what I initially proposed! I'm not like that, and I'll take on board your criticism. Which I've done.


    What bike is it?
    Aprilla 125cc, cost about £2k+ brand new

    Don't chance a motorbike tyre that would be stupid.

    I take it you don't know how to remove the wheel and take it to a garage, that would be the easiest option. Then book it in for mot.

    I am guessing your riding a 125 or a 50 (due to cbt). For a rear you'll probably be about £60 and front slightly less for branded tyres, though you've not said what bike it is.

    You said proper bike maintenance comes with the qualification of which allows you to ride bikes bigger than 125cc.

    You're in control of a vehicle which is capable of 60 mph, and you think only owners of big bikes have the qualification. Okay the majority of bikers do, do there own maintenance if there not capable then feel free to put it to somewhere.

    Report my post if you want your comment was silly, it was a valid point.

    Maybe you should write a strongly worded letter to whoever accredits the CBT test and/or petition the government to change the legislation for learner motorcyclists.

    The motorcyclists on the road are the kids who have stolen my motorbike twice before (locked on my drive), once to rag around the park and the other time to get home after a night out. On both occasions they very kindly left it in the park for the police to pick up and charge me £150 to release it, plus the repair costs.

    Or the motorcyclists are those who speed past at 1am doing about 50mph on a 20mph residential road. Some also have no helmet, or no padding!

    It is capable of that, but I do not travel on roads which warrant going over 30mph and nor do I break the speed limit.

    Well I say that but I once nipped into Stratford and ended up on the A1 which was effectively part of the M1. I had lorries overtaking me on that part of the road

    I'm a person who has access to a car but uses a 125 to commute to work and occasionally my partner's house because its a cheaper. That's all. I carry out checks which are probably above and beyond what 90% of vehicle owners do, and that's fine by me.

    He has changed tyres and other parts, told us and his dad has helped keen to learn.

    Next year he'll go up, hopefully to a bigger bike at 19 according to him, though does drive a car now.

    Motorcyclists who 'don't care' about their bikes beyond dropping it off for an MOT once a year often end up injured or worse.
