Default max tire height

This may be a stupid question but here goes....


I am shopping for new wheels. I run a 32x14 goodyear stiff sidewall slick. I noticed on Summit's page in their description for convo pros that they have a max tire height of 30 inches. I also noticed they say that Weld draglites not to be used with a tire over 31 inches I think....my question is WHY? Obviously lots of people run tires bigger than this...at least it appears they do...the "good" wheels such as Alumastar and the Magnums do not list this limitation. What is the thinking behind this?

Wow,I never knew that.Gonna have to do some research.I don't guess they are afraid the centers are to weak to hold a taller tire?

From what I understand "olds48" is right on this. The wheels are not rated for alot of weight to be put on the centers, maybe because they are a 2-piece aluminum wheel? Not sure. I was thinking they listed these limitations mainly for a 4x4..?

COULD BE...but how does the tire being taller add more stress to the center? Obviously the big tires weigh more on a scale but I don't see how it would effect a wheel center...unless like you said to prevent big trucks from using them. I know a guy with 32 x 14's on a set of convo pros...and there are probably more WELD Draglites out there on bracket cars than any other wheel probably.

I know a guy with a tube frame Beretta that runs 5.30's that broke a Bogart wheel. Busted the center right out of it when he launched. It didn't tear up the car but he said first thing he thought was broken axle...he was very lucky he didn't crash or rip the side off of the car.

A taller tire would put more leverage on the wheels center.
Not sure how much it effects it, but it does.

so you think it is a legit concern? I know ( at least I think I know) I have seen big tired cars with thye convo pros and for sure there are a bunch of em with the Draglites.

The thought of forking out 400 bucks a wheel for the Magnums or AlumaStars kills me.

But if it is a real safety issue I will have to I guess...cause I can't stand looking at these old "Tricks" or "AutoDrags" or whatever they are any longer.

Well the info I had was from Summit racing website. I looked on Centerline's Website and they do indeed say "30 inch tall tire limit"

BUT they say that does not apply to drag slicks.
