Will this combo work

I have read alot of threads on this and i am getting close to pulling the triggeron some new rims and tires. At the moment i have 15" ralleys with 4" backspace and 235.60/15 goodyear eagle GT 2 onall four corners. At the moment the only issue is the drivers side front will hit the wheel house bolt dips in the road and both sides will rub the paint off the frame rail at the stops.
What i am wanting t do is go to American racing Torque thrust D's all around. I would like to use a 7" rim with a 225/60/15 tire but the rims i want only come with a 3.75" back space, is that going to cause me any issues? On the reAR I AM wanting to use an 8" with a 4.5" backspace with a 255/60/15 tire. My concern is with the front and the backspacing so any clarifacation on that issue would be great. I just love the old school look of the torque thrust d's with the grey centers especialy with a Marina Blue car. Let me know if you guys have any thoughts and thanks in advance. Mike

Re: Will this combo work

3.75" BS on 7" front rim sounds too little and could leave the wheel/tire sticking too far out. I have 7" rims up front and run 4.25 BS with no issues what so ever. I run 225/45/18 tires up front which makes my tire width 101mm (225 x .45). Your tire will be at 135mm (225 x .60) which will make it even wider (with less BS) and could cause you rubbing.

Re: Will this combo work

Should i go with a 6"wheel ? What do you do when the wheels you want dont come in the size you want?

Re: Will this combo work

I think you will be fine.
The 3.75 backspace will move the tire 1/4" more under the car; plus your 225 tire is slightly narrower.

I've run 225/60/15's in the front on 15X8 with 4" backspace - no problems.

And the "225" or "235" designation is the width of the tire in millimeters; it doesn't change with the aspect ratio - 60 series vs 45 series.

Well, I botched that reply. Not sure where my brain was....yes, 101 vs 135 is the tire sidewall height NOT the tire width which is 225 in your/mine case. So, the difference is the .50" of BS between you (3.75) and I (4.25). In your case your 225 tire will be .50" closer to the fender lip than mine.

225/60/15

225 is the tires width in mm (225/25.4=8.858")

60 (.60) is the side wall height (one side, so you need to X by 2) (8.858"x.60=5.431"x 2=10.629")

Then add the rim diameter 10.629"+15"=25.629"

So that tire is a theoretical 8.9" wide by 25.629" tall

Re: Will this combo work

My concern is not being able to get a 7" wheel with a 4" backspace. They only come in 3.75. Will going to a 225 instead of a 235 keep it from hitting the bolt for the wheel house on the drivers side? I have 235's on 7" ralley's with a 4" backspace now.

Re: Will this combo work

.25" of less BS is 6.35mm. Going from 235 to 225 tire will buy you 10mm less or 5mm less on each side of the tire. So you are narrowing the tire by 5mm on each side but you are giving up 6.35mm/.25" of BS, hence pushing the tire more towards the outer fender. If my math is correct then 225 tire sitting on a 3.75" BS rim is actually closer (1.35mm) to the outer fender or fender bolts than a 235 tire sitting on 4.0" BS rim.

Re: Will this combo work

I would really like to use those Torque thrust D's or the Torque thrust orriginals but the back spaceing i need just does not work out. I can't afford to have my front tires hang out any farther

Re: Will this combo work

What are you folks running on the front in a 15" wheel size and tire. I have all the threads on the pages above and not alot of them list tne back spacing of the wheels and the tire size.

Re: Will this combo work

Why not just change the bolt to a recessed allen or torx head bolt. You could even just remove the bolt, grind the head flat, leaving enough to get a wrench on and you should be fine.
