Car tyres question.

Why?A bit expensive as well.Even if there were four 80 rated tyres on, at 450kg each, that's 1800kg.The car only has a GVW of less then 1500kg, so they're still within rating.I'd do the same as the op, unless I was going to be running with a heavy load in the back and the seats down all the time.

The maker specifies 84 rated tyres, its on the B pillar sticker, i'd be very reluctant to go below the makers specs.

Each to their own, i once had a write off accident recovered to my house, the very first thing the insurance assessor did was to closely examine all the tyres closely.

Camskills currently showing 84V/W rated Yokohama Sdrive and Vredestein Sportracs at £58 and £60.64 respectively.

Our VTS is on 84W rated tyres.

We put it on Vredestein Sportrac 3's because the noise from the OE Michelins was awful and they torque steered badly, no regrets with the Vredesteins.

Try Camskills Mytyres and Tyremen, i have bought from all three over the years without any problem.

torque steer has little to do with tyres and more the different length driveshafts that are needed to connect the gearbox to the wheels

And don't forget that the weight rating is the maximum continuous load at the tyre's maximum continuous speed.

And I suspect that tyres are made to actually be able to handle a bit more.

However, if the car manufacturer quotes a particular rating, there is probably a reason for this, and I wouldn't go below it. If there was a higher rated tyre for the same or a lower price, though ...

Thanks for all replies.

Think I'm going to go for two Vredestein 84V tyres for the front & put the front tyres that are already on the car on the back.

Will eventually get two new ones on the back as well.

** Checked rating on my car & it's showing as 195/45 r16 80v.

Torque steer went with the Michelins, as did horrendous road roar.

Is that whats on the B pillar label, if so 80's are fine?

Ours is the 1.6 HDi so could be a lower load index needed for the petrol model.

Michelins on car, poor grip, torque steer.

Vredestiens fitted, good grip, no torque steer since.

No loss of grip no torque steer.

I can't help it if it doesn't go with the theory, in practice this is the case.

Nothing to do theory at all its a form of black magic called moment of inertia, part of the all evil magic called physics.

How come? I though that all the weight is on the front, so need 84 rating on there.

fwd cars under steer, fitting old tyres on the back could apprantly cause over steer with no warning. Never witness this personly but what I was tought in my young days.
