225\45\15 Fit GLHS??

[trannybuster]

Or would 215/50R15 be better? Some bulge is okay. I want to keep the stock rims.

[contraption22]

225/45/15 would be a problem.
215/50/15 would be less of a problem, but still not good.
205 is as wide as i would go on a stock wheel.

Stick with the tire manufacturer's recommended rim widths.

Yup.:thumb:

I have 225 on my 6" wheel, but only because the tire manufacturer rim width recommendation is 6" - 8".
I checked on putting 225/45's on my 6" wheel last week and it's a no go. Manufacturer's recommendation is 7" minimum.

[Juggy]

the smaller the profile tire, the wider the rim needs to be.

you could prolly get away with 225/50/15

i ran that size on a few set of 6" rims

I ran 225/50/15's on my GLHS, on the original Centurions, front fit fine but the rear needed a spacer (1/4" is fine, 5/16" plenty) to clear the spring comfortably. It may have worked fine w/o it, but it was like right on the spring, I was afraid they would rub in corners.

+1 on the rear spacers on a lbody

definitely 7.0 minimum and honestly 7.5 or 8.0 would be better, heh. But very few people have 15s wider than 7.0 without spending bigger bucks.

[Force Fed Mopar]

They will work fine on stock 6.5" rims. I don't think I'd use them on 6" rims though.

[Vigo]

225/45r15 is a size that only exists for enthusiasts, in high performance tires that almost always run wide compared to 'normal' tires. in a low profile performance tire i honestly wouldnt put anything bigger than a 205 on a 6 and 215 on a 6.5..

im sure they'd go on a 6.5 physically but if you're buying that aggressive size of aggressive tire to get aggressive performance i think you'd be shooting yourself in the foot to squeeze it onto a stock 15x6 or 6.5.

[Force Fed Mopar]

Well, maybe a 45 series is different, but my 50 series worked fine on my Centurions. Tread was flat at 35psi, had good traction and even wear. And I drove the shyte out of the car too :nod:

I agree that proper rim width is better, but not every one has the money to buy another set of wheels (not good ones anyway), or perhaps someone would like to run them on a restored car w/ original wheels. Obviously anyone who is seriously tracking the car will buy the right size wheels.

[Vigo]

AND the right size tires for their wheels. Ive got a story about going from 205s to 225s on a 6.0 (and a more aggressive tire model to boot) and how it ruined the fun of driving the car.

In the real world, being fast is based first on being comfortable you can predict how your car will react to a given input. When your tire is moving laterally all over the rim because its too narrow, you won't be able to drive fast for fear of misjudgement and subsequent death. Steering response can become vague, indirect, and inconsistent.

205/50 or even 215/50 would be great visually and physically on a 6.5.

I think GRM iirc had an article recently where a narrower section width model of the exact same tire on the same rim allowed the car to run faster because the driver was able to drive it closer to its limits.. wish i could say what issue it was.

Im not saying dont do it. Im just saying dont do it expecting a wonderful result.

Any special place that folks are getting spacers for their wheels?






Just to let people know, 225/45-15's are now available as street tires.

true, but the rs-2 is rated at 200 treadwear, and the rs-3 is 140. They're street...legal. but they wont last long. They're basically autocross tires. And the only other tires i know of you can get in 225/45r15 are autocross slicks.

Yes you're right, they won't last long. I'm guessing 20k miles, if you're really nice to them.

As for spacers, i would try ebay. If you have a plasma cutter or a torch, cut the middle out of some old rotors. :)

[Force Fed Mopar]

I think Carquest carries spacers, it's where I got mine from.

[ShelbyTC16v]

I did find this on FWD performance. I'm just wondering if I need to use longer studs. I haven't put the 225's on the car yet. I'm hoping I don't need spacers, but that is probably hoping for too much.

Thanks for all the advice, Im gonna stick with the 205's. I want the car to as safe as it is fast.

You will need long studs with a 5/16 spacer. I was only able to get about 4 threads on a set of aftermarket wheels usling them.

That's just great. :rolleyes: I just have a feeling those 225's are gonna rub. Maybe I'll get lucky, but I won't know for a while.

My 50 series fit w/o rubbing in the front, but the back needed a small spacer, I think 1/8" would be fine. It was real close to the spring, close enough that I couldn't see a crack between the two. I couldn't hear any rubbing w/ it jacked up and spinning the wheel by hand, but I'm positive w/o a spacer it would rub the spring in any sort of cornering. A 1/4" or 5/16" spacer should be plenty to keep it clear though.

Did you check after running the car through some corners? No contact even with maybe a little tire flexing? Just curious.

[Force Fed Mopar]

No, I actually didn't run the the car with the 50's on the the rear, I had test-fitted the 2 off the front to see how they would fit, got the spacers ordered, then wrecked the car before I could buy two more 225/50's for the rear :( The 50's are low enough profile that they don't flex much though, I'm positive they wouldn't rub w/ a 5/16 spacer.
