Do you recall what they were asking for the 37x13.50x18 STT Pro? My local guy is at $365 each mounted and balanced. I want to compare to see if this is a good price or if I should try to push him for a better deal.

After running 34's on my stock 18" sahara wheels for a short time, I decided to sell the whole set. The prices for a good 18" MTR tire in a 35" let alone a 37" were outrageous.....

Try to sell the 18's on Craigs and get a solid set of 17's.....my 2 cents.

In this case, I priced the 37x13.5 on both 17 and 18 inch wheels and the 18" version priced out $5 less on the STT Pro at $365 each, installed and it the door with cash payment.

I've got a set of 37*13.5-17 STT's in the driveway that are load D, it may be a typo on the internet.

The 13.5 is a lot of tire if you don't need it. Good luck in your tire search.

They look like a gift from God on this JKU.

The 37x13.50-17 is on this yellow Jeep. Sexy!

Run the spacers. It's really hard to find a wheel with the necessary B.S. needed, unless you go Beadlock. Also, that's a very fair price. I have ties to the tire business and cost on that tire is around $340. I just picked up a set in a 37x12.50x17.

Pricewise that ain't too bad then. You will be lugging around a lot more weight at 13.5 wide though I'm sure...

Guessing you have the old STT, not the new STT Pro we are talking about in this thread? Unless Coopers website has been wrong since the tire was released.

37 /12.50R17 124Q D2 BSW
37 /13.50R17 121Q E2 BSW
37 /13.50R18 124Q D2 BSW

I was getting total out the door quotes with rims and certs through Discount Tire Direct. They price match, had discounts for forum members ($50), for a set of tires ($40), for a set of rims ($50), and free mount/balance for the set, so can't really compare to your quote.

Before the rebate, the 37x12.50x17 tires were 320.19 each, the 37x13.50x18 tires were 330.19. (the local shop offered to knock $100 off the price for the set that was sitting there, but it was cheaper to quote through discount direct)

I believe that I will order the 37x13.5-18, move the spacers from the D30 to the PR44, and see how it goes. I really wanted to wait a year to do the Redneck Ram Assist, but I guess I'll learn really fast how bad is is/isn't here in a month or so. I am putting the synergy sector shaft brace on as well the track bar frame-side brace with Synergy track bar and drag link. I know that the sector shaft brace will not help steering, but hopefully it keeps the gear box alive for the summer until I do my next set of upgrades in 2017.


Quick Reply: Will 37x13.50-18 work on 18x9 5x5 wheels with 5" backspace?
