In an effort to clear up many discrepencies and bickering as to what wheels & tires will fit your SHO, this thread will give you a pretty good idea on what will fit and what will not.

See below - 2 threads worth of information combined. Keep in mind, offsets will differ. You will need to play around with them to make sure the fit is ideal for your car and your mods.

**NOTE**
Some tire sizes above 235/xx/xx will most likely require rolling of the fender lips and or a radical offset.


Stock offset for all year SHO's is 42mm and the bolt pattern is 5x108 (~4.25")


CLICK HERE!!!!! for a good explaination of +/- offsets. (Thanks Wuzzer)

CLICK HERE!!!!! for a spreadsheet that Fred Hurder put together a few years ago that explains known tire/wheel combos.


CLICK HERE!!!!! to calculate speedo differences with different wheels



Generic wheel information by year:

- '89-'90 "Basketweave" wheels are 15"x6".
- '91-'92 non-directional ("Canadian") slicers are 16"x6",
- '93-'95 directional ("Italian") slicers. 16"x6"
- '96-'99 "5 star" design. 16"x6.5"


As for aftermarket wheels:

Various wheel combos have been used, some more successfully than others. 16x7, 16x8, 17x7, 17x8, 17x9 (w/ spacers), 18x7, 18x8 & 19x? have been used. Offsets typically vary from ~+37mm to +45mm.

A note about determining proper offset. As the wheel width gets WIDER, the offset needs to get SMALLER. This is in order to keep the wheel away from the body. (Thanks Mr. A)

YES!! Some Volvo wheels, Jag, Lincoln, and Thunderbird wheels will fit. ...Remember 5 x 108"....

Mustang wheels WILL NOT! fit on a taurus, their bolt pattern is different (4.5" bolt pattern) you can find places that make replica's to fit specific bolt patterns but dont expect to walk into Ford, buy SVT's and have them fit...

The tire information below was taken from 2 threads in this section as well as some information off v8sho.com. These are the most popular wheel/tire sizes.


Gen 1

225/50/16 - stock rims
225/55/16 - stock rims
225/60/16 (VERY close to rubbing on rear of Gen 1)
235/45/17 - some rubbing issues
235/40/17 - Trimmed rear wheel wells

Gen 2

215/65/15
215/55/16
215/60/16 - Stock rims
225/50-16 (track only)
225/55/16 - Stock rims
225/50/17
235/45/17 (about 3mph off at 75)
245/45/17
235/40/18


Gen 3

205/65/15
215/60/16 - Stock rims
225/55/16 - Stock rims
225/60/16 - Stock rims
235/35/19
235/40/19
245/35/20 - WHY?



You running specs that arn't listed?? Post here or PM me with that information and I will add it to the list.

**** AS A GENERAL WARNING TO ALL FORUM MEMBERS, PLEASE BE WARY OF BFG KDWS TIRES. THESE TIRES HAVE A LOWER LOAD RATING THAN STOCK TIRES AND HAVE BEEN KNOWN TO BLOW OUT ON ALL YEAR SHO'S. MANY MEMBERS HERE HAVE HAD THIS HAPPEN, PLEASE MAKE YOUR SELF AWARE!!! ****

the biggest thing you need to watch out for is the offset. Do you have any more information on the wheels?

As its stated above +42mm is the OE offset

"Offsets typically vary from ~+37mm to +45mm."

22.5lbs is a heavy ass wheel!

I don't forsee an issue with fitment with those wheels, with stock suspension I'm sure it will clear fine ..

235/40-17's on 17x7.5's, I believe they are +42 offset. Very low suspension. Rear wheel arches trimmed. With Eibach's or Intrax, the trimming should be unnesessary. Plan on trying 245/40-17's this summer.

Great write up, by the way. :thumb:

I know you don't exactly have all this information right there at your desk, but could you also include the weight of each stock wheel at the top of the thread? I just want to know for sure what would be a lighter wheel if I go for aftermarket rims.

stock weight

What is the stock weight of the wheel and tire on a Gen2? Sparate and together.

Thanks, SHObhakti

Sooooo, 18x7.5" with a 52.5mm offset on a Gen I is a no-go?

The wheel I have on my SHO are Enkei PK6 17"x7" with a 38mm offset wrapped with 225/45/ZR17 Falken GR "Beta" tires and I've had no problems with them at all. I got them off discounttiredirect.com all together mounted and balanced for $1055 with lug nuts and spacers.
:nono:But I warn others about discount Tire's lug nut kit:
It is a Gorilla wheel lock kit that uses a key on every lug nut and the key is a piece of garbage. I have sheared the steel side wall of 3 keys with less than 10k miles since I put the wheels on. I have never used an impact on them. The company only covered 1 replacement under warranty and said that they're rated at 150ft/lbs, but I'm not strong enough to apply that torque by hand and I broke 3! I just keep buying more @ $10 a pop, until I get a better kit. McGard doesn't even have a kit for me, I went to the factory near me and they measured it with a micrometer and searched all of their catalog and told me they have nothing to offer.

You will need approx. 1/2" spacers with that much longer studs, minimum, or wheel adapters.

The larger the offset the closer to the strut you are. Test-fit with some washers / spacing material to find the correct spacing you want (do not torque-down or ride on washers as spacers, you'll center-bend the wheels & ruin them).

You're always better off finding wheels that are the correct fit if possible, vs. running spacers.

I agree, I don't want to have to piece something together...

question......i am buying a set of 17X7 wheels and tires, the tires are new but they are 205/45/17. does anyone know if this size is even worth being on an sho. they are new so i was just going to drive on them for the rest of the summer/fal then put my snow tires on in the winter. they are roughly the same width as 215 60 16. i just want to know if anyone has ever run them.

You don't want to go narrower on treadwidth, you want to go wider.

205/45-17 = 24.26" dia.

215/60-16 = 26.15" dia.

You're going to gain at least an inch in wheel gap, to start. Your car may accelerate better with the smaller wheels, but you also run the risk of upsetting the ABS system as well.

I ran 235/45-17's on my 17x7's very successfully, dia = 25.32".

yeah i want 2254517 or 235 but im just saying for now its not going to hurt if i run those tires right? my car has koni/intrax with one coil cut in the front. im not worried about the wheel gap. im worried about the performance. and the speedo being inaccurate. my abs system is inactive right now too.

If you are not at the same diameter tire, of course your speedo's going to be off.

Trust me on this: 235/45-17 works on a 17x7. It's close enough to stock that you aren't that far off on the speedo, and your ABS works. You gain tread width, and the sidewall is also talled than the 225/45 will be, for a slightly smoother ride (remember the tire acts as a spring).

You should also confirm the load rating on the smaller tire, to make sure you're not risking tire failure.

You aren't going to blow the engine or anything running the little tires, but you really don't want them on this car.
