Those are the Larger R4 Tires... I'm almost having second thoughts on if I chose the right tires this time around. Because I do a lot of work on paved driveways, and I have to drive up and down the road quite a bit... seems kind of like a knobby ride... not bad, but not as smoothe as the turfs... Also, Turf Tires don't wear out like R4's do on pavement.. so I'm wondering how soon It is going to be before I have to buy new R4's... I really like them, but they might be just a little too aggressive for what I need... my biggest thing is snow removal.. and most of it's paved.... always had turfs in the past, and they did me fine..... oh well, I'll keep them....
