Need help choosing the right size slick...
I want to go with the 26 x 11.5 x 15 Hoosier QTP but I only have a 15 x 8.5" Convo Pro wheel. Will it fit? The Hoosier website says it only needs 8 to 10 inches but Summit says it needs a 9 to 10 inch wheel.
Also, am I better off with a 26.4" tall tire with a 10" tread width or a 27" tall tire with a 9" tread width?
I'm currently running a tire that is too tall at 27.4" but my 26.1" drags I previously had were too short.
I want to go through the traps at 6500 rpms. If I go too tall, I won't be able to do it and I'll be sacrificing ET. The 26.4" slick should be the perfect height but if I have too much friction from a 10" width then maybe it is just as bad as going too tall?
Any advice?

Hell, I run 30x9x15's and 29.5x10.5x15s with 5.13 gears.

Woah!
I have 4.10 gears and with 15 x 7.5 Convo Pros and 26 x 9 x 15 Hoosier Drags I was going through the traps at 6500 rpm and trapping 117 to 119 mph. With the same wheels I went to 28 x 9 x 15 MT ET Drags and lost two to three mph in the same weather. I was only going through the traps around 5900 rpm. According to MT website, those tires are 27.4" tall, a full 1.3" taller than my Hoosier Drags were.
Over the winter I've lightened up my Z some more and did a couple little horsepower mods hoping to get another mph or two out of her. So I'm thinking on a good weather day, I could trap around 120 mph. Based on that presumption, I'm assuming the 26 x 11.5 x 15 QTP's wrapped around a 15 x 8.5 Convo Pro would work best due to the 26.4" overall diameter.
The 4.10 gears are staying until they break. That being said, do you think with the 26.4" tires I should be going through the traps close to 6500 rpm again?
Thanks again,
Derrick
