After several hours of research I settled on a set of retreaded tires from
www.treadwright.com. There's some obvious drawbacks to retreaded tires and its much too soon to say if the cost savings outweigh the shortcomings. Although not my first pick, I decided to try their 235/75 R15 (29") Crawler M/Ts. Cost was $87.00 a tire and shipping was around $75. Not too bad for a set of offroad tires. Several of their tires were on backorder so if you have any intent of ordering from them you may want to order several weeks to months in advance of actually needing them.
Just a side note here for anyone else besides me who is confused by the gibberish of numbers and letters designating a tires size. Tires are often identified by three numbers, using the above 235/75 R15 tire as an example the first number 235 designates the width the tire in millimeters. The second number 75 designates the height of the sidewall of the tire as a percentage of the width. In this case 75% of the width of 235 is .75*235mm=176mm. Therefore the sidewall height is 176 mm. The last number R15 is the inner diameter of the tire and the diameter of the rim in inches, in this case 15 inches with "R" designating the tire as a radial tire. So stupid.
The tires arrived within a week of placing my order and looked great. The casings (the portion of the tire that is reused on retreads) were matching, and looked defect free, no patches, plugs, etc. The tread of the tire itself looked fairly aggressive and had over 1/2" deep well spaced lugs.
Once mounted I immediately noticed there is some road noise that accompanied these tires. It begins as a low whir but as you accelerate up to highway speed it transitions into a noise that sounds a bit like a small jet taking off. It doesn't bother me..yet.
I only have one offroad test with them but as expected they do better then the four bald Pirellis they replaced. So thats good. I'll do some more "testing" later. For science.
I'm going to try and stay vigilante and take note on how the tires wear and offroad performance. So further "testing" will be required periodically.
