Your asking a bunch of guys that dont run or need competition tires if you should get them.
I run the 40in treps competition compound. Super big soft lugs.
I ran the same set for KOH pre-running, KOH qualifying, and 200miles in the race finishing 18th on the same 4 tires. Tires were about half tread with about 300 miles on them. The traction of the tire greatly improved as they wore down.
That day of wheeling might be more then most see in a year.
I chose the treps because at 20 psi they hold up to crazy abuse, and with the sticky compound were still crawlable at 20 psi. They didnt fold over on turns, and were not bouncy which helped for shock tuning. I think its the best fastest tire I can buy for ultra4.
I run maxxis tires on my dirt bike and quads, all for their soft thread compound and durability. No plugs in any of those 10 tires in several years.
Even with a racer's discount the Treps are the most expensive tire option.
Can you even get a set for $2400 as a non racer?
If your not racing and just doing rock crawling have you tried water in your front tires. At least to the top of the hub, or to the top of the rim. Water and stickies is like cheating.
