Default Re: Rim width?

I asked a similar question of Hoosier regarding their 30x9 bias ply slicks. Combined with my limited experience using 8" and 10" wheels with them, it seems that they grow more with the 8" wheel, and section width is about .8" less. The sidewall seems to work harder and wrinkle more with 8". I am told you can run the pressure up from 11 lb. to 13 lb. with the bigger wheel, but haven't tried it yet. Performance is similar and Hoosier confirmed that on slower cars there won't be much difference. That was confirmed by a former holder of the D/S record, who used up to13 lb.

I just bought a new pair, and got 9" wheels for them. My hope is that the sidewalls will be happy and I will get the best of the growth vs. footprint vs. section width. It is not as expensive for me to test as I use 20 lb. Marsh racing wheels (steel) for a nostalgia look/car. [I get them with centers for 5/8" studs, 45 deg. lug nuts such as ARP sells].
