Max tire width for PP wheels

[dsp4848]

Does anyone know the widest tire that you can fit on the factory rear 19 x 9.5 wheels without having issues? What about the front 19 x 9?

Would going wider in the back, to say a 295 or 305 width, require spacers or any other special part?

I've seen 305 DR's on the stock PP wheels with and without 1/4" spacers, with the spacers the tire was almost even w/ the quarter panel. I located some 19x10 look alike PP wheels, and I am thinking about running them w/a 5/16" spacer so the tires will be even with the quarter panel and leaving the stock width wheels in front with the same spacer.

Here are some pics of 295/35s on the rear GT PP rims. Just had them put on yesterday, no problems!

I want to do this when my original tires kick the bucket. I love the stock PP wheels but would like more width in the back....but I haven't found many tires in 295/35/19.

305 is max I believe.

You really shouldn't be putting passenger car 295's on wheels that are only 9.5" wide. 10" minimum.

285/xx is the widest passenger car tire that 9.5" wide wheels should ever have to support, and 9" wide wheels are good for up to 275/xx - per Tire & Rim Association tables.

A 295/xx LT tire would probably be OK'd for 9.5" wide wheels if you can find any, as LT's are designed to somewhat different needs and requirements and allow fitment to narrower rims. But Light Truck tires on a Mustang???

Why people are so ready to throw away any of the performance that their wide tires promise by squeezing them down onto too-narrow rims has never made much sense to me.

Because it looks better ^^^

 

[Norm Peterson]

See, that's what I don't understand. Why so many people consider a combination that's technically "out of spec" to look better when for a number of reasons it is an inferior solution.

If it's out of trying to re-live the 1960's when 6" was the "wide" wheel and tires were 82-series, with a few 70's starting to show up, and all tires had this rounded bulged-way-out-past the wheel sidewall shape, none of that is worth trying to copy today with tires that aren't intended to be installed like that. I am by no means suggesting that the other extreme - stretched out past max recommended - is any better. Only to use the tires within their intended design conditions.

305/35/19 looks awesome

Looks good to me

The view from behind looks OK because you can't see how narrow the wheel is relative to the tire.

Sorry, but in side view, that much bulge looks like what you'd see on a 1990's midsize sedan running 205/55-15 tires (same bulge/wheels sunk inside look, nearly the same sidewall height).

Anyone else put wider tires on yet? Post pics.

ive only seen 305s on the factory as the widest anything more buldges to much IMO

 

[Norm Peterson]

Simply put - for unrestricted street use anything wider then 285's on 9.5" wide rims is wrong. Appearance does NOT trump technical considerations and proper installation, no matter how badly you might like for it to.

I ran 305/35-20 555r Drag radials 24/7 on my 2012 Shelby with SVTPP . I believe the wheels were 9.5" wide in the rear. Minimal bulge and looked really good. Fairly functional, to a point... 690rwhp still would overpower them.
