It was really hard to get them on the rim, but if they will fit go for it...

205 on 5.5 ? hmmm, i don't wanna be anywhere near you when that tires slips off that rim (IMG:style_emoticons/default/huh.gif)

rule of thumb for tiresize:

a = wheelwidth * 2.54
size = a + (a * 0.25)

in your case:

a = 5.5 * 2.54 = 13.97
size = 13.97 + (3.4925) = 17.4625 = 175 tire

soooo, a 195 will still do, but a 205 is pushing it ...

the above is not for the absolute max. but for a good fit. sooo, add a size or two and you're at the max. for that rim ...

I do not know if rivieras are 6 inch or 5.5,,,but they have held the hoosiers for three years now with no slip ups, but they are only used in autocross, no track time. Just cant spring for the 7 " rims...

BTW Third place Im impressed

They will fit but its not the best for autoxing as the sidewalls are soo far in. Not the ideal way to do it but it will work.
Try to find some 6" rims if you can or have them welded up out of steelies. Go though the classifieds and see whats available like Panasports, Centerlines as they look good and fit right.If doing it on the cheap, go for it.

Yeah, I ran Dunlop SP8000's on em too plus I AX'ed with them. It does work just isn't the best cuz the sidewalk is pointing in to the rim.

I did it successfully too, but I probably wouldn't have if 195/60R15 DOT-R tires were still available. I subsequently went to 15x6 and then 15x7 wheels, all with 205/50 rubber.

7" is 177.8mm so you still have over 1" of sidewall/tread bulge even with the 7's.

Yes, but... the fit is way better with a 7" rim, don't you think Chris?

Yessir, 7's are just about perfect with 205's. I'm gonna run 205's on my 16x7's as well. I don't think I could squeeze the 215/40 Hoosiers under the fenders, even rolled n' pulled. So 205/45's are my plan.

Thanks, Sean...if I say so myself, it is coming together nicely. The pedals are from AJ-USA. The gas pedal is a complete replacement pedal, which is what drove me to buy them in the first place -- when I bought the car, the stock gas pedal was completely shot so I talked myself into an "upgrade". The brake and clutch are covers, that screw onto the (drilled) stock pedals once you remove the rubber pads.

Chris Reale,
Dave Ellison runs his Kuhmo's on some steel rims that were widened to 6". Pretty nice set up for AX rims on the cheap to stay 4 bolt. Might ask him where and who did it for him, that way tires and rims won't break the bank and get you racing.

I did the 5 bolt conversion on the cheap:
$600 for the rear hubs, bearings front & rear, 4 discs, studs
$450 for a set of nice 6x15 Fuchs (shipping included)
reused the Dunlop SP8000s

I ran across a smoking nice set of 15X6 fuchs for 800$ tonight. They are a 8 out of 1-10 on the nice scale.

Using the 5.5 rim with a 205.. completely defeats the reason to run a 205. You end up with LESS tire on the ground than you would if used a 195. The sidewalls end up cupped badly.

Save your money Chris. 6's are in your future.
