Tom.. What transmission are you running and what rear gear ratio? I was thinking that I could get a 29in tire under my car without mini tubbing it, but I don't know. My rear is narrowed 3in per side like yours, but my wheels are only 5in BS. I have lots of room on the outside of the wheel, but not much at all on the inside. I will probably end up running a 28x10.5W so that I don't have to make a gear change.

thanks boondiggys. Thanks for the props man.
ss2000 How are you man? I'm racing at Thompson this year. I'll be at PRP a couple of times.
W stands for wide. You guys need to look at your current sidewall width and BS. How much room do you have now with your current sidewall width and BS?

Right now I have about 3/4 of an iinch on the inside between the sidewall and LCA.. This is with standard lca's.. I do not have offset arms quite yet. I have 2-3 inches "i think" on the outside between the sidewall and the fender well lip which has already been rolled.
The car currently has 28x10.5 non W tires on it now. I am only running a 3.50 gear so I need to stay with a 28in tire unless I go with a 3.90+ gear later on. I'm pretty sure I could fit a 28x10.5W under it after I get the offset arms.
Tom, did you try to tuck the 30in tires BEFORE you put the tubs in and after you had the rear narrowed 6inches? With the 28's I should be able to lower the car a little bit more.

you can narrow the rear up to 3" if you stick with a 10.5" wide tire on a stock tub and offset LCA. if you are going to narrow might as well go for it and if you want a big tire later you have the option to mini tub. then you can look like tom the roofers car.

I had the 30" tires under the car but they just fit after grinding the frame area with the horizontal ridges and some massaging the wheel well with a BFH. The 30" tire I ran last year had a 13.1" sidewall width and I had approx. 1/4" clearance from the ground down frame area. I don't remember the LCA clearance but I know it didn't come into play at the time.

If your just looking for the deep dish look then get the rear shortened 3" per side and change BS. In my case I was previously running 7.5" BS with a stock rear end width, so If I would have shortened the rear 3" per side and then changed to 4.5" BS the tire would be in the exact same location. Right I just wouldn't have been able to lower the car with the big 30" tire without a mini tub and offset LCA's.

28x10.5W on 15x10 7.5"BS Prostars. No narrowing/tubbing. Just some use of the BFH and trimmed the rear bumper a little. Looks fine to me, but yeah, can't lower it much if I wanted to. If anything, the fronts are what stick out too much cause of the necessary spacers.

Does the rear have to be narrowed from the factory....or can you do it after.
Meaning...can I have my Moser 12 bolt narrowed now?
How big does the tire have to be to have to narrow the rear end. Would a 325 MT DR (15") need narrowing to make it fit well within the fender?

Narrowing the rear end has nothing to do with tire size. More like weight reduction and improving on the strength of the axles.
SJM can make a set of custom rims to get the tire centered in the wheel well. That doesn't mean you can run a big tire and not have to do some trimming or hammering.

I thought that people did it to fit more tire under the car?
Also....you are saying that it would be more money to have my current 12 bolt narrowed compared to just buying a new rearend??

wow lots of questions that can be answered with the search feature.
1) narrowing a rear affects the size of the tire you can run. tuck the wheel in too much and you will run into clearance issues. then you mini tub
2) you can order a rear narrowed as much as you want. cost is the same. weight reduction and stronger axles as above said.
