Tire size suggestions and brand

[Rory Christianson]

Can anybody suggest a front and rear tire size for me being used on 69 corvette stocker. Mainly heights is what I am concerned with front to back
And which brand you are having the best luck with ?

Thanks in advance

M/T on ten inch rim

[Myron Piatek]

Look at photos from national and divisional events. I think you'll see that Hoosier tires are the most popular. They have worked well for me.

Rear tire height should be as tall as you can go within the rules and not rub. (30" max.) A taller tire theoretically puts a little bit more rubber on the track. Then you can decide on bias ply or radials. Radials don't grow and will give more rpm's at the finish line. They tend to be .10 faster but more sensitive to track conditions. 10" rims with 9" tires is common.

If you have a consistent staging and launch rpm, try to chose a tire height that helps get/keep your reaction times within a comfortable margin. Taller will be a bit slower and shorter will be a bit faster. (Michael Beard can be more specific about the differences.) A 24" front tire may help a slow car/driver, but doesn't necessarily look good.

LOL Well, that's one way to pick a tire. If you look at winner's circle photos, you'll see that Fletcher "and a few others" runs Mickey Thompson tires.

Bias plys have more meat on them. They're slower than radials, but last significantly longer. M/T's don't require a lot of burnout, and I'm thinking my 14x32's will probably dry rot before I wear them out. LOL The M/T radial is more like .012-.013 quicker than a bias ply. I ran the M/T 3066R 30x9 radial full time when my car was a Stocker, even when bracket racing. Unless there was something on the starting line, or the cords were hanging out of them, they printed tickets like crazy. I've heard all kinds of numbers from people about tire life from radials. A lot of Stocker guys will tell you 40-60 runs, and 25psi. I ran mine at 18-19psi, and got 110 runs out of them like clockwork. Mine was still on a narrow rim too.

If you have a consistent staging and launch rpm, try to chose a tire height that helps get/keep your reaction times within a comfortable margin. Taller will be a bit slower and shorter will be a bit faster.

Remember that Myron is talking about front tires and reaction time. The reverse is true in terms of E.T. In general 2" in front tire diameter will get you about .012 in R/T. For detailed information, refer to my guest editorial on ThisIsBracketRacing.com (requires subscription).

Double-check and make sure you won't have any clearance issues with a large front tire, either from turning, or coming down from a wheelstand.

Just offering an observation. There are variety of reasons why people use a certain brand tire and, needless to say, there are many winners on M/T tires. Maybe I notice Hoosiers more because I run them, but it would be interesting to see the actual percentages.

[Alan Roehrich]

For that car, I'd suggest the Hoosiers. The 9"x30", on a 10" or wider rim. The lightweight radial C06 for going fast, and the bias ply D05(softest) or D07 for "bracket mode". You'll get maybe 50-60 passes out of the radials, more out of the bias ply. You do not need a monster burnout, quick and clean, go straight to the line. The 28"x4.5"x15" for the front.

There's nothing wrong with M/T tires. Or Goodyears, for that matter.


A few people get tires free, or even get paid to run them.

Stick? Which engine?

[Bob Pagano]

L-88 James, not sure what trans...... Auto

[james schaechter]

It sure would make sense to look over Dave Casey's deal. If a ten inch rim fits, that would be awesome. I doubt if cost is the main consideration on tires here, but with an auto, it ought to hook in a mudslide! Maybe have a set of radials and bias ply tires mounted and at the ready. With all the engine setback and the weight that will be stacked up in the rear, hooking should not be an issue! Sounds like fun!

Get a big ole worn out set to figure out how much clearance you need when you are doing the body work.
