Hi
My 2007 2.0 diesel x3 has stock 17" rims with non rft tyres. Tyre profile is 55. I think the ride is way too soft and bounces you all over the place. I dont really want to go down the route of overfilling the tyres with air all the time so was looking for advice from others who may be on 18"s with a lower profile tyre. Keep in mind im in the uk and our roads are basically the same as a building site.
My e90 3 series is on 18's with 35 profile and the ride is great, its a petrol though
What would you recommend for the x3?
