Rim width?

art leong · 12-29-2012, 07:48 PM

I'm going to buy a pair of Diamond Racing Spun Wheels for my circle track 13 x 8 x 20 tires I can get the backspacing I need and they are only 14 pounds each.
I wish I could use a radial tire. But I have to be happy to even have a biased ply that is 20" tall.
If I go taller I kill the car at least .15 and 2 mph. Which is fine in protect mode
I've tried ABA testing of 6 inch rims and 8 inch rims and the 6 inch cross the finish at least 200 rpms higher. So the narrower rim (in my case) grows a lot less.
These are not ordinary slicks there is almost no sidewall (3 inches).
