I currently am running an 18" rear wheel, I ride in SoCal high desert 95% of the time. Also, I like to hillclimb. At present time, I'm using a Maxxis Maxx Cross IT. I'm thinking about switching to the IRC M5B. What do you think? Also, which front tire would be a good match?

The M5B is great in either deep endless mud or sand.

I don't think its that great for anything else. It has a very soft sidewall (think wrinkle wall on a dragster) and is prone to flats if you ride in rocks.

I'm sure others will pipe up and say they've had no problems with them, thats my experience with those tires.

If you stick with Maxxis, try an SI on the rear instead of the IT. I also like the SI on the front.

+1! I had the sensation of a flat tire on anything but deep sand or mud, and I experienced a few flats on rocks even with higher than normal psi for my weight and riding style. If I was doing a race in the Sahara it would surely be a top choice!

I think the M5B works better on lighter 2-strokes. Use to run them quite a bit on a yz250 (130 -18" rim). That bike had enough motor for the 130 their kinda big.

I have the same set up on my 06 450. I think the IRC is a great tire. I dont think so highly of the Maxxis. It wears good but sucks for traction.

I use a Dunlop 756 for the soft stuff and a Dunlop 739 for the desert. If the ground is wet I'll run whatever is there.

A friend of mine changed the front tire to a 20". and loves it. He runs a 756. That set up is real nice when the ground is dry.

IMO, 756's are pretty good up front when they're new, but they only stay like that for about 2 rides. 739's are useless except for supermoto. Whenever I encounter one, I remove and discard it immediately. Actually, I tried using one to mount tires on, but I couldn't make it stop sliding around on the floor.

I find that for the kind of soils I run in in the SoCal desert/high desert that the Dunlop 952 works better than anything I've tried, and lasts as long as anything, too. The rear is far better in sand than a 756. It's a little more subject to tearing in rocks than a Maxxis IT, but otherwise is a much better tire, and it's extremely versatile as to soil type. As you already know, the California high desert is a mix of soil types that is nearly impossible to pick a single good tire for. It ranges from fine DG gravel (or coarse sand?) to packed DG to rocks to hard packed sediments. Nothing really covers all that perfectly, but the 952 deals with it better than most at a fair price.

In the front, it's between the 952 and the D755 so far, but I don't feel like I'm done looking.

What are the advantages of running a 20" front?

I like the Dunlop D742FA in the front, the Bridgestone M404 for rear and have had good look with Michelins which seem to wear very well and provide great traction.

My riding partner liked the wider track of the 20" tire. It felt different to me. I guess its what works for you.
