I have had a Bridgestone M78 which is a hard terraine tire. I have been running it for about a month and a half. I tend to ride in really rockey and hard clay area. As far a wear, it is ok. I know that a lot of people don't have too many good things to say about them. As far as price goes, I think that I paid about $55.00 for this tire. I don't know if this is your price range, but I think that you could do better. The next one I buy will be a IRC M5B. This was recommended to me by several people. I don't know the price of these though. Good luck with your search. :D
Check out the Cheng Shin C755's. You can sometime's find them for around 30-40 bucks and they are a real good intermediate type tire. I've got a friend that runs them on his CR 250 and mainly rides a loamy outdoor track and they get tons of grip. Plus they seem to wear really well.
I use the 756's on my 36 hp / 26 ftpd of torque 220 in very rocky terrain and they hold up very well, I haven tried the s12 or m12's yet but a friend uses them on his yz400f and they hold up very well.
I also want to get a new set of rubber for my 220.for intermediate/hard pack. I was leaning toward the 756rear whats a good match for the front? Are the stock tires that bad? (K695 rear K490 front) also whats the deal on a 110/100 rear? Thanks Darin
For long wear, the IRC's are very difficult to beat. The M5B that KDX1 refers to is the soft-terrain tire, but it still lasts really well. The intermediate IRC is the Vulcanduro VE-33 (rear) and VE-32 (front). IRC uses a really hard compound. Their sizes tend to run a little bit smaller than others, so you would probably step up one size.
A lot of it depends on your bike and what works best. I tried the Michelin M-12 on my 400EXC and absolutely hated it, especially in anything that even hinted at being slick or muddy. For my bike the S-12 or the Bridgestone MT-16 seems to work best so far. I'm gonna try the 756 this weekend and see how it works.
I used to run the IRC's on my XR 250 and they were terrific for that bike, but the VE-33 I have on my 400 now just doesn't seem to work well with the motor, and it also wore out prematurely. You can also get longer wear if you'll go up a size, but you must be careful about getting too much tire on a bike, where you end up with more tire than you have motor.
