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.

Mt buddy,Tommy,has been running 33x10.50s on a set of convo pros for years.My neighbor Kirby has a set of 31x14.5 on a set of convo pros that go on his 61 Galaxie.I wouldn't worry about it,personally.Just my opinion

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. :D

If it were me I would run them. I don't think the use in Drag Racing would hurt the wheels. On something with alot of weight, like a 4x4 or something you pull with it may be something to consider.

According to the manufacturer, there is a height limit for conventional tires but it does not seem to apply to slicks. Here is an excerpt from their website:
Featuring Center Line's classic racing wheels with the convulted outer. These top-selling designs have left their definitive mark on the street and track. This is a modular aluminum wheel manufactured by riveting two wheel halves together back to back. Wheels are light weight and designed to go fast and look great. These wheels fit the vehicles listed below and much more. Just check your bolt pattern. Typically to fit any diamter wider than 9 inches requires careful measuring and/or modifications to the vehicle. Call us at 800-345-8671 x5 to discuss any questions including fitment advice...we have lots of it as well as diagrams. Center section of Convo Pro is a satin/machine finish; the outer is brilliantly finished to a hi-polish shine for a striking contrast. 30-inch max tire size (OK to run taller drag slicks). 1525 lb load rating per wheel.

I am in a similar situation but going to be using 33x21.5 Mickey Thompson sportman bias ply street tires.

I was planning to go with Centerline Convo pro's but now wondering if I have to go with the much more expensive Weld Aluma stars?

What rims are guys using with tall street tires?

I'd weld two stock 15 x7's together before I bought anything from Centerline. THEY ARE SCUMBAGS

ok then....well I guess that also leaves the Weld Woodward RT's. Not much else to choose from.

Is anyone else out there running a back half car with street tires over 32", there must be.

Any advice? The Welds are fine, just wanted more options for style.
