Will these fit OK

[BLH2]

I would like to put on new tires. Will Mickey Thompson Baja Claws 37x13.5 fit OK. I know that 37's fit but I am not sure about the width.

I have Toyo's 37 13.5 MT. If you use stock rims, they are narrow and cause the tire to squeeze in, making it taller and skinner. The tires rub on the front stabilizer bar and on the rear frame and air bag sensor. I had to reposition the air bag sensor to keep it from being broken when I went through ditches. I was told that if you have coil springs the spring rubs on the tire in the back. After market rims which are wider will not help. They let the tire widen out compared to stock rims. The tire will still rub on the sway bar and the air bag sensor as well as the inner fenders in the front. Stick with the stock rims and be prepared to move the air bag sensor arm to the inside of the sensor and you'll love them. (Unless you bought narrow rims with 4.5' backspacing, that would allow the tire to move out from the frame without making it wider and rubbing on the inner fenders. Haven't tried this so your own your own here) Good luck.

IMHO, I have these on my truck. I am giving you real life experiences, you may come and measure if you want...narrow rims cause the side wall to squeeze in making the tire taller and narrower It does bulge past the rim which protects the rim from curbs..

4 wheel parts manager told me he had to take a set off of H2 with coil springs because they rubbed a groove in the tire. May have been the frame. (Just what I was told.)

Wider rims will not stop the inner frame rubbing, plus they will add rubbing to the inner fender.

IMHO

If true, I've been under a misapprehension. I thought that narrower rims, within acceptable limits, reduced the chance of popping a bead for two reasons: (1) the rim/tire seating is protected from by the slightly-bulging sidewall, and (2) narrower rim exerts more lateral, inward pressure on the tire where it's seated - i.e., the contact force between the tire and the rim is greater, especially at low pressures.

I really don't know the science behind it, but while you are putting more force on the seat area with narrower rims, when aired down you have to counter that with the pull from the sidewall bulge and the fact you now have a sharper angle between the sidewall and bead, causing the tire to deform away from the bead.

You're blinding me with science! Makes sense though.

Breaking beads suck!

Another reason to wheel with Adam...

Phil I'm with You on the tire width. The narrower the tire the more it bulges. Could be exceptions but, I have run manyy 100,000 of thousands miles on farm and road etc. My guy has been in business for 30 years and quote the specs on every brand almoct that exists.

He has always drilled into Me if You put a big tire on a narrow rim it turns it into a ballon and the bead wil pop under stress.

As i mentioned there may be new rules or guidelines I'm not familiar with but, I'm usually very good at researching what i do as all the old hats here know. sometimes to the point of irritation but, they have put up with it and have helped many. But, the purpose of puttinga large tire when i was looking to do it was to filll in allthe wheel well. The tire specialists told me just put it on a 17" and it will look like you could float the thing across a creek instead of fording it.

This is just what i learned from allot of years of buying tires for farm trucks, tractors and combines. The principal remains the same with them as does a truck or car. I have wanted to put larger tires on tractors before and h told me the same thing it will work for a while but, under strain and load the tire will pop off.

So you just have to go with our best info and use someone You trust in the business to direct You i Your choice. Plus things may have changed since it has been a whle since i retired from farming at 40 now 49. So I'm sure i learned something along the way. But, seriuoly You have to do what makes You happy and make decision with someone You can trust and allot of experience.
Good Luck with this
