Tires rub, is smaller tire ok?

1988 930. 225/50/16 in front, 245/50/16 in back. Bbs wheels.

Like some other posts I have seen on here, my right tire sticks out a bit further than the left. There was a prior fender bender, mild, which was repaired.

Drives me nuts. Frame shop checked pick up points for a-arms, and they were within 3 mm or so. Not perfect, but close.

The front tires are pretty dang wide. Was the stock size 205?

Would 205s fit the current rims, or would that look odd?

There are lots of ways to make a tire stick out further, but is there any way to make it stick out less? I can add a quarter inch spacer on the left for looks, but then both tires would rub...

I am really hoping not to have to buy new rims....

Any help appreciated. Thanks...

Bo

Check the ET on the wheels (might be different side to side?). ET must be really low for that narrow tire to rub?

You can run even narrower tire if you dont swap rims. Front has no spacer IIRC on 88 models so you cant make it fit better. I run 255 front and dont rub on my 79 so its not the tire width but the ET of the wheel. Do the fenders look symmetrical or can the rubbing fender be pulled a bit more out?

Most of our cars are not perfectly symetrical due to the fact that the flairs where manually welded to the fender, so there could be some discrepancy...; but regardless, you should be able to stuff 315s in the rear and 255s up front w/o problems assuming the wheels backspacing, spacers and tire profile ratios are correct.

I run 255/35 18s in the front of my 930. They do rub a bit at full lock on the inside of the fenderwell. Not a big deal, but there is rubbing.

Guys, what offsets are you running??? Perhaps I just need new wheels...

I will post my offsets later, when I get a chance to measure...

I run wider tires than you by far on a narrow body Carrera 3.2 without rubbing.

Here is my offset:



Running Toyo R888's 235/45-17 and 255/40-17

Had slightly rubbing in the front. Solved by replacing shims with selfmade ones to reduce steering angle:

your offsets must be way off. A 930 can fit bunches more tire than 225 up front.

I have the same size on the front of mine and I have tons of room in every direction

+1 It seems like people can run up to 255 in front and 315/335 in the rear, depending on the tire shape (different manufacturers have slightly different sizing and tire shoulder shapes).

Sorry for the delayed response...

Finally had a chance to look at the wheels. They are bbs 8x16 ET 11...

Does that sound right for the fronts?

I see pics of cars where the front wheels look like they are recessed about an inch. Mine are pretty much flush with the wheel arch.

If I take a ruler on the drivers front, and place it against the top and bottom of the tire where it protrudes most, on the left the ruler sticks out 1/32 past the arch. On the right, 1/4 inch. Thats at zero camber.

I have read many posts on here where one wheel is 1/4 inch off on one side or the other. On my car though, BOTH sides will rub I suspect on hard cornering...

is an 8x16 ET 11 the wrong offset?

Thought I would update some old threads...

Finally got new front tires...

Kuhmo 205/55/16 to replace the 225/50/16. They fit fine on an 8 inch rim, look fine, and don't rub. I really didn't want to roll my fenders, if I could help it.

So for anyone looking at this as an option, it works fine. This also opens up your tire selection choices also. The thread contact patch is only 0.5 inches narrower.

As an aside, kudos to Tirerack. Not sure how they do it, but I got my tires with 36 hours at my door step. I was shocked.
