Thread: Tyre size

Some of this is down to the tyre volume decreasing with larger wheels but of course some of it relates to the tyre itself. My experience with 19s is road tyres and with 20s Nittos (as a passenger). So I guess a better comparison would be say KO2s on both 18s and 20s to eliminate the difference a tyre makes. Russrobe's comparison between different tyre sizes in 18" suggests tyre volume plays a part but I'm not sure if there's tyre differences in his comparison too.

Hope that makes sense.

Thanks Scott.

That's helpful. Sounds like it's not a problem, more a slight softening of responsiveness if that makes sense. I ordered GOE rims to be able to get a more comfortable ride, even if it's marginal, for SWMBO who has a lot of health problems. I'm looking at 265/60/18 in Hankook ATM RF10's, Bridgestone Dueler A/T 697"s and possibly the Michelin LTX Force which has a "cushion guard" layer to minimise road vibrations/shocks (if you can believe the statement on their web site). Don't do any off road driving ATM unfortunately.

Thanks for your reply,

A 'P' rated tyre will give a much more comfortable ride than an 'LT' rated tyre of the same size.

But if you want a robust tyre,you may have to go LT.

I would also experiment with pressures,as they affect ride comfort as well.

Thanks Paul.

I had a slight bump against a kerb going through one of those rotten calming devices and split the sidewall on a tyre with only about 5000km on it so was looking for a more robust tyre to avoid this type of problem. Lost confidence in H/T tyres because of that incident. I'll give the pressure change a go too.

Appreciate the advice.
