Tyre load rating, can someone please have a look?

and a higher side wall may allow the tyre to move more on the rim - don't think this is a good thing when you're pushing it 10/10's.

You manage that with tyre pressures mate... You need tyre roll to maximise grip and you manage tyre temp, roll, graining and maximise grip with tyre pressures (as well as suspension setup).

It will still do the same with a tyre and the correct pressure, just varying degrees. You shouldn't over inflate a tyre either.

I personally wouldn't go lower than a 40 series on my R32, but did get lightweight wheels and maintained the same tyre profile as OEM as it's easy to scrub if you go any wider.

So I agree it's purely for looks.

Yup! Most race cars run higher profile tyres than their street going cousins. And if you look at the most advanced race cars in the world, in Formula 1, you'll see they run very high profile tyres.

That's pretty good. Comparing a tyre profile of an F1 car, with virtually zero suspension travel, to a road car with a couple of inches of suspension travel.

Perhaps a more realistic comparison to our road cars for normal daily driving, if one has to be made, would be a WRC car in tarmac spec. What do you think?

Not sure how much has changed but in 2000, front travel on an F1 Jaguar was ~25mm, rear was ~80mm.

[Rocket36]

there's a lot less travel in the suspension of F1 cars in 2009 than there has been for many years.

[G-rig]

Racing tracks are usually pretty smooth too.

F1 cars may have huge profile tyres but i reckon the sidewall strenth is a bit better than street cars. Bit of a pointless comparison really, as pointed out.

Thats my white R36 wagon with the black rims....car looks better when its cleaned!
