TYPE R TYRES

I have bought a 98 Type R V4, I hadn't noticed until a friend pointed out that the tyre profiles were different from the back to the front 45 back and 40s front. He told me that it could ruin the diff due to different rotation speeds.

Please could someone tell me if this is true.

Many thanks.

Re: TYPE R TYRES

Thank you for your response Bob.

Forgive me if I'm being a bit naive, but there surely must be a certain degree of latitude because of tyre ware. For instance, if the tyres on one axle had to be replaced, being on the legal limit, but those on the other axle still had 1000 miles left in them.
According to my rough calculations, that would create nearly a 2" difference in tyre circumference between the two axles. The difference between 40 and 45 profile would be approximately 2".
On the strength of that, is it then almost as damaging to replace tyres on just one axle as running different profiles?

Re: TYPE R TYRES

even if you have exactly the same tyres all round, you will find that the rears wear out quicker by about 2mm on a classic.

I recommend Falken 452 over the Goodyear Eagle F1's for 2 reasons, Falkens are a lot cheaper and provide a lot more grip in all weather conditions.

Why such an indifferent response?
I was simply querying a valid point!

You obviously rate Falkens. I looked at them about 2 years ago for my MY99 Turbo, but was put off by negative reviews.
I ended up with Michelin Primacy Pilots which came with a set of wheels I purchased, but to be honest, other than lower road noise, they didn't seem any better than the outgoing Kumas.

funny I have Falken 452's fitted to a MY99 Turbo for almost a year and use it everyday, no issues at all. There is also another user on this site that has them fitted to a newage and used them in soaking conditions on a track.
