What tires sizes are reccomended for 18x7.5 43 18x9.5 40? I'm really low about 2.5-3 inches and want to know if I'm risky out back.
Was thinking 215 /40 255/35 but the 40 offset has me worried and I don't want a lot of stretch. I'm rolled front and rear.
Currently I'm on 17x9/10 bbs lm 42 and 50 offsett. How much risk is the 40 out back? Will I rub and have to raise?

Current height and setup

 

Would like to close wheel gap some will the 18 do that or is lowering needed?

 

What wheel gap? Overall diameter will stay the same provided you pick correct sidewall height, you will just have more wheel and less tire. If you are worried about rubbing, start with a 245/35 rear. Difference compared to your current setup is minimal, any rubbing should be able to be corrected with a little more negative camber or slight fender pull.

 

Thanks for reaponse. I have about a .50 inch gap out back. I'm currently -2.3 camber out back I suppose I could bump it to -3. Def do not want to pull the quarters.

 

Also I saw 245/35 on the nt03 too much stretch for me.

 

Looks like ill have to run 245/35/18 in the rear at rhe height I want to avoid issues.

What should I run up feont? 215/40 to keep in line with the rear 245? Its a 7.5 43 up front.

 

No. If you run -3 out back you can run a 255.

The front you could go either way. I probably would just go with a 225, simply because on a 18" there is less sidewall and this adds a little stretch and clearance over the 17 counterpart.

 

Thanks man I ordered 225/255 will report back on what happens later this week I hope

 

Keep the 17s on

 

As promised a couple pics. Went with 255 and 225. Camber is front -2.2 rear -3.2. Rear still rubs on hard bumps. I'm rolled and trim and relocate tab. Any suggestions? I've trimmed a lot but still rubs where bumper meets quarter. Help!!!
