Hi, anyone running a 305/40/18 on a 9.5 wheel?

Thanks Pete

That seems a too wide for a 9.5" tire. I'm pretty sure the tire specs on a 305doesn't warrant a 9.5" tire. If you mount it, there would be alot of tire going inward, so to speak, from the rim not being wide enough. I'm no expert though. Just my $.02. I previously had 305's on an 11" rim. Not to mention a 40 sidewall for a 305 is pretty tall.

Nitto's size chart recommends at least a 10.5 wide.

Nitto says 10 to 12, will a 1/2 make a big deal? They are exactly what I want as far has size goes 27.75 high. I'm looking at Centerline rims and they only go up to 9.5.

Thanks
Pete

A 9.5" wide wheel isn't 9.5 wide. Measured width is what tire manufacturers go by. My guess is a 9.5" wheel is around 10 1/4" measured width. Recheck fitment specifications for specified tire and then measure from inside of lip to inside of lip on wheel.

It will probably work but I wouldn't go outside a tire manufacturers recommendation. That could bite you at the wrong time.
