I have a set of 16" GTU/TII s5 wheels i need to put new rubber. I think i plan on running 225/50's and i know it will clear the rear suspension no problem but i want to make sure it clears the front suspension. Or can i step up to a 245 sized tire?

 

Running 245/45/16 isn't a problem on the rear for me, just the front is..had to take out some plastic crap around the wheel well for the tires to clear..

 

from what i have read 225s will clear the front

 

I'm running 225/45/17s and they're fine... I've seen people run 235s but I don't know what they had to do to get them to fit.

there is a wheel and tire section that would probably be much more help.

 

not without a small spacer. Ask me how I know.

Honestly, I was tracking the car on 225 Bridgestones, and felt the tire roll over onto it's sidewall a lot. Might not be such a problem in the rear, but I would honestly go with 205/55/16 in the front and possibly 225/50/16 in the rear, as long as you can set up the camber properly. I felt that while the 225 has more lateral grip than the 205's, it's sluggish in transitions and I would rather use 205's all around, unless I was running big power that justifies a 205/225 setup.

Just my thoughts on this after running 225 all around.

 

ok right now this is just a bolt on car i just want to have the tires to support future upgrades

 

i run 2555016 drag radial on mine, with no rubbing in the wheel well and the lower control arm. iam using a stock turbo 2 wheel

 

It depends on the individual tire. Different brands and models are not the same, even on the same sized tire.

I am running 225/50/16 Summitomo HTR+ on S5 Turbo wheels. The front required a spacer -5mm- to clear the front strut and longer studs to accommodate the spacer.

The fronts now rub slightly on the fenders. I intend to roll my front fenders, but I haven't gotten around to it yet.

I will do 215/50/16's next time. Straighter sidewall, better response, no spacer, no rub, slight speedo error of 1.7%.

 

I currently run Toyo 215/55-16 front and Toyo T1S 235/50-16 on the rear. As soon as the weather warms up new tires will be going on BFG G Force 215/55-16 front and Continental 235/50-16 rear. I've run 245/50-16 on the rear with a matched (diameter) front tires, but don't remember the make, many years ago.

 

225 is the widest I'd go, personally. 235 may be doable, but a 245 is a fat-*** tire for that wheel.

 

I personally run 215s in front and 235s in the rear on stock-offset 7"-wide wheels

 

I did 225s and they rubed in the front
