289 FIA Rear tire sizes

[Bguetter]

Guys, i have a standard fox width 3-link rear axle and FFR 15" Halibrand wheels. Will a 295/50/15 tire fit the 289 body? I see that 275/50/15 is recommended but no tires other than drag radials are available in that size. Thanks!

I couldn't find the bigger sizes in street tires either for my 289. In looking at the Cobra book, I noticed a good shot of Bruce Meyer's black early cobra with 245-60 15's on the rear. That's what I went with, and it seems to work well with a 3:08 gear ratio/ 4 sp BW T10. They do not fill up the wheel opening like the big meats do. 235-60-15's are on front. If I change the rear ratio, I may consider larger rear tires if I can find something.

Dan from factory five emailed me today and said 275 is as wide as we can go with the 289 body.

Exact tires i'm looking at Japollon, thanks for the picture. Did you have to use tubes?

[japollon]

I do not have tubes and have been checking to see how they hold tire pressure over the past two months. So far, they have not lost even 1 psi! Erik T from this forum has had the same experience. Yes, it does say right on the tire that they are "tubed" tires. However they see to work fine without. Joel
