Those are the same tires I use on my xt. I have about 3500 on a set currently, I'll replace the rear within 500 miles, but I expect to get another 4000 out of the front. I plan on ordering them in threes, less than $100 shipped for three tires that should be good for 4000 miles seems like a good deal to me.
I honestly ride probably 80/20 most of the time, but the last few months has been more like 50/50, nothing hardcore, but I feel like the SR244 has good manners on pavement and gravel roads. I thought that the rear seemed pretty loud for the first 200 miles or so, I'm curious to see how the next one is. I'm also going to be installing a Tubliss setup at that time, not sure what, if any, impact it might have on tire noise.
