Can just any normal tire shop mount a 31x18.50 tire?

In your experience, can just any normal tire shop mount/balance a big prostreet tire? I usually like having Costco mount my tires, do you think they can handle that or is a special tire machine required? I'll be mounting 31x18.50 MT tires and tubes on 15x15 weld wheels.

I take mine to Discount tires because I have a friend that works there. Mounting the tire is not bad. We have to remove the cover on the balancer to balance my tires but they are 33 x 22 x 15. Then have to trick the magnet for the machine to spin.

Maybe with your tire being the 31 x 18.5 it will fit.

May look for a decent 4x4 shop ?

When you mount those up, be sure to put some baby powder around the inside of the tire carcass and I powder the tube as well. It keeps the tube from 'binding' against the tire/wheel during inflation.
I mounted mine in my garage with no problem but had to go to two shops to get a balance. If they use stick on weights when they balance your stuff, don't let them put the weights on in one long strip. The weight is not put in the spot needed if they use one long strip. Have them put the weight on in shorter strips, side by side, at the spot the machine is calling for. Tires with tubes CAN call for a lot of weight. If it calls for a huge amount, bust the bead and spin the tire 180* on the rim and try again.

Dont let them stick the weights to the out side and specify to them because they might.The sell a thinner stick on if you have non stock breaks.

Re: Can just any normal tire shop mount a 31x18.50 tire?

Okay a little follow up:

Called a bunch of tire shops and none had a balancer wide enough to do an 18.50 M/T. The mention of them unbolting the hood to balance the tire damn near made them laugh. Even the local 4-wheel parts said their balancer only holds a max of a 15" wide tire. I found one shop that would though. It was US Tire, who does a lot of big rig stuff. They said they'd balance them on their big semi truck balancer. I get there with my wheels only to find out that their "big" balancer is broken, so they sold me on some stuff called "equal." It's a sand type concoction that is poured into the tire and is supposed to dynamically balance it as it rolls. It's mainly used in the trucking industry and is used by a lot of the 4 wheel drive guys with monster tires. They said that if I'm not happy after I try it, they'll balance them for free as soon as their balancer is fixed. I researched it a bit when I got home and it looks like a good product. We'll see how it goes.

I'm curious how this holds up under repeated hard acceleration.

one of my local Goodyear dealerships does mine, no problems. I've had them done a few times.

Re: Can just any normal tire shop mount a 31x18.50 tire?

Greg,

Equal is often used in big rig tires and large RV's, I have it my RV tires which are 295/80R-22.5's and it works great but these tires run at 120-125psi vs. the low pressure a crinkle wall slick would run at. That said, I find it hard to believe their isn't a speed shop in Modesto that can't point you to someone that can do the tires. Check online for big rig tire shops especially out by Hwy 99.

Re: Can just any normal tire shop mount a 31x18.50 tire?

Find a shop that does sprint car tires they are often way wider than what you're dealing with.

I thought you were running tubes? Did they use Equal with tubes? Wish I would have saw this thread before I would have recommended not using equal. It is ok for big rigs (still not really recommended). Getting it out of your tire will be messy too.

Royce brings up a HUGE concern.........Where is the equal ?? If it's between the tube and casing there is NO WAY it can migrate and work to balance the assembly. I assume they blew it into the tube with the machine. No way will you ever get it out of the tube. If you opt for spin balancing at a later date, you will need to replace the tube. And ABSOLUTELY use weights on the outside of a combination that wide and heavy. By only applying weights to the inside, you won't get a true balance. Seeing weights is part of the price for using tires/wheels that wide. Chrome pound on weights are available and look nice enough.

As far as being a good product in a tubeless tire, I have used it for 17 years in my semi tires and have had many inquiries over the years as to where I have my tires balanced. They always wear flat and round, not cupped or choppy, so as far as I'm concerned the product does work well.

Good input. Good thing my tires don't have tubes
