9" or 10" wheels

Rusty Gillis · 02-14-2018, 08:40 AM

I'm going to update to new lighter wheels on my 1969 B/SA Mustang. I will be using Hoosier radials and was wondering if there was an advantage using a 10" vs 9" wheel.

Thanks,
Rusty

Go for the 10 inch.

Ten inch Rusty....better footprint IMO.

Exactly. I have 8" and 10" wheels for my Nova with 9" Hoosier radials. The 8" are only used for winter storage now.

My original plan was to get 10" but I thought I would check here first.

Thanks for your help,
Rusty

My son and I have nearly identical D/SA Demons

He runs 10" and I run 8 1/2" on Goodyear 9" Radials

They 60' the exact same 1.33 to 1.35 any give day

He feels that his car is more stable last 300 ft.....He has driven
both cars a lot!

Of course he feels his car is faster too......But it is NOT!

I've never noticed any difference on the timeslip or seat of the pants. I'm always looking for the most even wear across the tire.

With a 10" wheel and running 17 psi, I'm still wearing out the center of the tire quicker than the edges. I'm getting nearly 250 passes from a set, so I can't really complain.

A wider wheel adds stability to the tire sidewall. If you get out of shape the wider wheel will reduce the flexibility in the tire sidewall and give you a better chance of a smooth recovery.

It all depends on the tire but a rule of thumb is 1" of wheel for every inch of tire.
