I am in the middle of a build right now and a question I should have answered awhile ago has come up again....Tire size. I was going to put a 302 in it so 33's wouldnt have been a big deal, but I would love to race BITD so it requires I stay with a 6cyl.

The truck will be in the 7200 and 1450 class. Right now it has the stock 2.9 (till I blow it up in testing the chassis) but I am looking to put a 4.0 in there to stay BITD legal. I have a bunch of 33's, but I have them sitting next the truck and they look awful big for a 6cylinder. What is everyone else running?

My Ranger is a prerunner/chase and street legal. I run 33's with a 2.8L/5 speed and 4.86 gears. It will run 85 on the freeway and has more.

33" tires will be fine with a V-6, we race with 33's and a stock 4.0. It's commonplace for people to race on 35" tires.

What gear ratio do you plan on using in the rear end.

Agreed... 33's are the smallest you should go especially if your gonna hit up a few races here an there, throw some taller gears in that rear and stuff the biggest tire you can get away with in those fenders

Well its a race dedicated race vehicle, I shouldve mentioned that. Nothing street legal or original about it anymore except the original C-channel Rails (Soon to be boxed in), and the motor (Soon to be replaced).

Gearing? not entirely sure yet, something close to 5.0 in the 9".

I guess I was looking at the difference in what was on the truck (28") and the 33's I am using for mockup (plus its easier for me to get them than 35's) and I know how much bigger tires make a truck with little power gutless. So in the tight stuff I should be ok then?

not at Gutless as you may think, you def need to regear the rear Diff, like many have said, at least a 4.56 minimum, and prob 4.86 if you race it more than on road.

Sweet. No road whatsoever except what may be part of the racecourse or going up and down my street for the initial shakedown, lol. Thanks for all the info, it really alleviates some of my stress in the build. Another question I, I might just start another thread but...

What is the average wheelbase people are using for 7200/1450? i know the rules for 7200 specify no wider than 85, with the 9" I have I will be around 80.

not sure really, we are doing a kinda 7 open class ranger with about 124", not sure about the 1450 class 1972 Ford we are doing, I cannot remember off hand.

someone will know though, just check the V2R thread and look for the 7200 guys and ask them.

I think you'll find most of the 7200 class truck have a wheel base of between 120" to 125." The WB for 1450 will vary due to the large variety of vehicles racing in the class.

I would not go any higher than 5.0 gears we ran 5.60's in our truck w/33',now we run 6.0's w 35's.Don't be scarred of the 4.0 SOHC it's a strong little motor. That's what most of the guys in 7200 are running,built a little yes, but strong!

I am a big fan of 33x10.50 a lot guys run the wider ones, but i like the lighter weight with that diameter.
The rules say 85 so I would go 84.5 just to be safe. i have been told that it is 85 to the outermost part of the tire.
You are correct, from the widest part of the bulge on one side to other. Which doesnt make sense I think, It should be the contact patch, but what do I know.
