What's the Bolt Circle on the Delta 88s? I think my current wheels are 14x7...I know they're 14" at least....would upgrading to 15x7 wheels hurt much? I am looking at some Cragar wheels that aren't too expensive and are chrome with a simple but cool design. They only sell em' in 15x7" and 15x8"...

Uh...how many lug nuts are there? I've never seen beneath the hub caps, my dad took em' off once....but uh..yea....

is it a 5 on 5.5" bolt pattern....for some reason that rings a bell...maybe it's not the right bell though

They're 5bolt... But I think the bolt pattern on the late 80's deltas are metric or something, someone once told me. Its quite common anyways, with FWD rims... I bought mine last year, but I never needed to know the bolt pattern, they looked everything up on the computer. Go to TIRERACK.com and select your car, and it'll show you everything about it. 5 on 5.5 is a GM pattern, but its too large for these cars. I beleive most 1/2 ton trucks with 5 bolt were 5.5".

TIRERACK.COM doesn't even show the right size....it shows 15" or 16"....it doesn't even give 14", which is what size my wheels are...STOCK....so...any better reference sites? Tirerack sucks...

funnily enough, i looked at my spare today wondering about the stud pattern and it is 5 stud, but i couldn't tell you the exact details

unfortunately aftermarket wheel selection for GM front wheel drive cars is pretty limited because of the 5x115mm bolt pattern, GM RWD cars are 5x4 3/4" and wagons are 5x5". i was looking into it at one time, i saw a nice set of American racing 5 spoke polished wheels that came in 16" and were the correct bolt pattern.

Brando, you'll most likely want to stay with the 15x7 wheel, as its already wider than the stock 15" wheel, which if I remember right is either 15x5.5 or 15x6. Make SURE the offset is correct on the wheels you're looking at, otherwise the wheels will sit out away from the car too far, and may rub on the fenders. Cragar and Eagle, as well as other companies, have wheels available in the correct bolt pattern and offset for your car, most of which use a stock type acorn chrome lug nut to hold them on.

Hey stroker, do you think it would be possible for Alero rims to fit on my car? I still have the factory tires and rims, and hubcaps , But I really like the Alero rims.

This is a great site regarding bolt pattern and fitment issues!

Brando,
I when out to tire rack and looked around a bit (sorry about your bad experience there). Searching on your car for tires showed that you were right on the 14'' wheels. 205/75-14 (this should be marked on your tires). All direct replacement tires are 5.5 rim width, 8-inch tire width and outside diameter of 26.1.
All wheels are 5 X 115 mm with 38-42mm positive offset. That’s about 4.5â€

Digging this topic back up, yea....it is possible Cutlass95Ciera, I am looking at some chrome Aurora rims, and they are 16 x 7 and 5-115mm bolt pattern. Alero rims are probably the same...

You would need some smaller tires, 205/55-16.
