Front tire height

[roccodart440]

Currenttly have been runnign a 26x7.50.

Has anyone tried a 28" tire under the front? And how did it fit?

What model and year?

What is the current clearance between the outer edge of your tire and the front bottom fender lip?

I've found 225/60/15 is max for 67-69 Dart and Barracuda on a 15x7 rim with 4.25" backspacing. And in some cases that is too close.

I have a 69 Dart

A 7 inch rim with 4.25" backspacing is 1/4 over what the normally accepted offset is for our cars which is 2.5".

I will have a 5.25" rim with 3.5 backspacing

The tire you mentioned is 25.6" tall. I run a 26x7.50 now.

26x7.5 Is that a MT drag tire? MT lists that as having a section of 6.3"

225/60 is about 9" wide.

5.25" wheel w/ 3.5" back has 3/8" offset and results in 3.15"- 0.375", or about 2.775" tire outboard the rotor face.

His 7" w/ 4.25" back has 1/4" offset and results in 4.5"-0.25", or about 4.25" tire outboard the rotor face.

Assuming the same suspension / brake combinations your tire is farther inboard by about 1.5", so it likely clears the front edge of the wheel opening, where if his tire was as tall as yours it would not.

Turn your tire in to where the outside edge lines up with the front fender edge of the wheel opening, that is one tight spot, then turn the other way and see how far you clear the bolt at the back of the wheel well opening. That will tell you how much clearance you have.

Either way 26" will be pretty close on an A-body.

Maybe I'm missing something here but backspacing to my knowledge is from the mounting flange to the inside edge of the rim. A 5.25" rim would yield 5.25"-3.5" leaves 1.75" of rim left. Where are you finding an extra inch of rim?

My 26x7.50 were on a 4" inch rim.

My 26x7.50 were on a 4" inch rim.

You mentioned having a 5.25" rim, I assumed was with your 26" tire.What tire are you going to run with your 5.25" wheel? What wheel width and offset is on the car now w/ the 26" tire? How much clearance does your 26" tire have?

205/75-15 ran that size for 15 years.

New wheels in front are 5.25 wth 3.5 backspacing. Tires are 26x7.50 sportsman fronts.

I wanted to know if taller tires would fit.

The MT 28x7.5 is about 0.6" wider overall and 2" taller than what you currently have on the car. Do you have 1-3/8" to 1-1/2" clearance around the perimeter of your tire at rest and full lock? Do you have 3/4" or more clearance to the fender lip on the outside? Key places to check will be as the tire sweeps past the front edge of the fender, the rear where the bolt is, the frame at the inside back as you turn all the way out and your fender brace. Easiest way will be with no torsion bar so you can check full extension and full compression.

Sorry I can't answer your question directly.

This helps as now I know where the problem areas will be. I'm going to run my 26's until they're wasted. I'll check those areas.

Was hoping someone would say that they ran the 28's adn it worked or didn't but your post was helpful.
