Tyre sizes help please!

Be_Happy

Hi can any mechanic/tyre fitter help me here.

We are in the process of trading in our Peugeot 107 for a Hyundai i10. Peugeot has almost new winter tyres and we are hoping that the tyres will fit the Hyundai, but are pretty sure if we ask at garage or tyre fitters, we'll be told they don't and will be pressured to buy new tyres.

Peugeot 107 tyres are 155/65T14 and Hyundai info says its tyres are 165/60R14.

Thanks

What does Hyundai specify in the owners handbook for winter tyres? If they are not a stated size you may have insurance issues in the event of a claim.

Haven't got the owner's handbook yet. We don't get the car till beginning March. First step will be to get the winter tyres off the Peugeot and the summer ones back on. At the poor trade in price they gave us, the garage are not getting any extras with the car when it goes in.

Was concerned about the insurance issues, had realised there could be a problem.

Should be fine - one size either way is very unlikely to be a problem for the rims. The slightly narrower tyres will also help a little if we do have more of the white stuff.

The rolling diameter of the narrower (and higher) tyres will be about 3.5mm more - equivalent to less than 2mm worth of tread wear - so in theory will make your speedo read slightly lower, but not enough to worry about - it's well within the difference between new and worn tyres anyway.


eta: from the insurance POV they shouldn't have a problem as long as you let them know.

They will fit on but with a mismatch in width and sidewall aspect ratio. Nothing major. Keep them and decide later or sell them.

There is sod all difference in the revs per mile between the two tyres so there shouldn't be any gearing or speedo problems.

The load/speed rating may be different though.

As said above, it may be best to confirm with your insurers that they are happy with the change.

Most general car winter tyres are only rated up to 112/114mph - of course you can get higher rated variants.

Most Insurers from the ABI list don't mind too much as long as the wheels tyres are no larger than existing:

The 155s do 948.4 revs per mile, the 165s do 954.5 revs per mile. The speedo difference is 0.3 mph between them so less than the difference between new and worn tyres. The winters are narrower so no wheel arch clearance problems which may be a possibility if the other way round.

Thanks for the very helpful link, Vikingaero.

Get the peugeot tyres swapped for part worns

keep the winter tyres in storage for next winter on the Hyundai.

The wheels might not fit on the hub though so might want to check that otherwise some new wheels might be needed.
