Impala SS wheel questions

So I'm almost finished polishing up my Impala SS rims for my 94 RMW and I have a few questions. What plain center caps fit these rims? I have looked on ebay, but when they say fits impala SS what year are they talking about? Would some one be able to post up a link to plain ones that fit? I want to be able to put buick stickers on the center caps.
Question 2, Tire sizes. stock 225-76-15 show a diameter of 28.3 inches on th4e tire racks web site

225-65-17 show a diameter of 28.5 inches on the tireracks web site

215-65-17 show a diameter of 28.0 inches on the tireracks web site

How much will .2 or .3 of a inch effect the indicated speed and will there be any other problems, and what size tire would you go with?

Those tires are too tall (and narrow). The stock height tire that works on SS wheels is 255 55 17. Optionally, you can use a 255 50 17 (stock SS tire), and many use the shorter 235 55 17 (including me). I just got a set of 225 60 17s for someone, and they look like they will work ok.

For caps, there are many choices. 94-96 SS, later FWD Impala, Malibu, Monte Carlo. All will accept a Buick decal.

Also 4th gen Camaro caps.

And Chevy Venture caps give a flat surface, but I think the chevy logo is raised, so they might not look good with a Buick decal over them.

you have me confused. the stock height of a RMW tire is 28.3 inches. .2 inches is going to be too tall? the what about the one that is .3 inches shorter? the 225 60 17s are a full .7 almost 3/4 of a inch shorter than the stock height yet also go on 6 to 8 inch rims with a tread width of 7.6 inches compared to the tread width of 7.5 inches on a 225 65 17 tire that also is recomended for a 6 to 8 inch rim.

SS wheels are 17x8.5, for the record.

thanks

I should also mention that I still want to be able to tow a boat with the car or pull a lighter trailer with 2 dirt bikes. Is 55 series side walls going to be able to handle this?

I am running the stock SS tire size of 255/55/17 and they are almost an inch shorter than stock. Had to have the computer reprogramed to compensate. Pulled a 6X10 enclosed trailer tipping the scales at just under 4K with zero issues. I still have the same tires (minus 1 from a flat I ran on) 3 years later.

If i had to replace all 4, i would go with a 28" tire.

I as well run a 235 55 17. With a simple reprogram the work very well. I pull a 1700lb camper plus 500lbs of stuff and 600+lbs of people and they do just fine.

I use 225/60R17. They work well for me and looks fine. I am using the Michelin Energy LX4. Really nice tire. Silent on the road and comfortable. (OEM tire for Lincoln Town Car note: a HEAVY car so weight is not a problem.) Also, this tire offers a whitewall in that size.

What 28 inch tire would you consider running?

I'm not particular about my tires..... Just want something closer to stock height to fill the front wheel well.

IMO you will have zero issues with a quality built 255/55/17.....

would you also think that either size would be fine height wise? What size are you running?

For many of us, tire height depends on what day of the week it is and what the weather is like. ;-)

well,.
255-50 17's
285 40 17's.

The other halfs OCC we run 255/50 17's on the front, and 275/50 17's on the Rear with Impala SS Wheels,and have no problems what so ever

Who has good prices on Center Caps for these wheels?

I run 235 55 17s on my 91 OCC. I like them as they are cheap and plentiful (vs the stock SS tire size) Actually a 235 60 17 would be alot closer to the stock size (.2) vs. and inch.

Main reason is I'm buying take off tires that are used. I just paid 180 installed for a set of 4 Goodyear Eagle RS-A with 70% tread (price of one new tire) .

If you go that route only buy the tires if the guy selling em will mount and balance (I got burned on a set of 4 where 2 had slices in them and didn't find out till I went to mount them 6 months later (DOH!)).

Yes my speedo is off a little but it tends to keep me driving a little slower
