This has 225's on it last time I saw it. It's all in the offset of the wheel. Like said before simmons are good as they make them to what you order. I suspect that the guards may be rolled or at least lipped as well.

The distance between wheel to wheel is the wheel track. My 1000 ute has 225's on the back, they don't rub but i do have the bolt on flares.

i have 215/45/17's on my coupe...my problem is actually the springs..i have room to fit 225 under the rear but the just touch on the springs...215's look big on the coupe

Sedan can only fit 205 width in the back, with rolling the guards.

Perhaps utes have more room?

in this photo i have a set of 17 x 225s on the back and they had about a bees dick of clearance

ive seen 9's all round on 1200's before, although they were running very low offsets and rolled gaurds/flares. I think a lot of people underestimate the amount of wheel you can get under a 12. Depends what you want i guess.

you could just squeeze 225s under the back with the right offsets and slightly rolled guards, if you pump/flare the guards, minitub it and move the leaf springs you could fit some bigger rubber.

isn't wheelbase the distance between the front and rear wheels? my utes got 205's on the back with no mods but i'm not sure about the widest that will fit.

whats the widest tyre i can fit under a 1200 ute withou cuting the chassy?
