Hi Seery, I have really enjoyed my ITP 27" XTR radials. I have over 145 hrs on this set of tires and really like them.They still look new.I have 9" wide in front and 11" wide in back. They are 6 ply and my sidewall rates them at495lbs at 7 psi max. I keep about 20 in the rear or they will sit somewhatflat.I keep about 12 in the front, This over inflationworried me at first, since the machine is heavy but I have hauled about 600 to 800 lbs with no trouble.They rideand handlewell.I have to travel about 4 miles down a paved road to reach the end of this place and the radials handle like a dream. I can split down the gravel road or across the pasture it doesn't matter to me or the RTV. These tires are easier on my neck and back since the bumps aren't as rough as with the stiffer tires.Somewhere in my tire search, I read that the 27" have 1/8" deeper tread than the 26" and the 27"setonly cost$15 more. That is a lot more rubber so I went with them.{ $ 400 delivered}. Before the XTR's I had replaced my WS with a set of plain mudlites with polished rims. These lasted hundreds and hundreds of hours before finally developing knots. They were near the end of useful life anyway. I intend to keep the WS mounted on the factory rims for emergencies or summer use. It is hard to go back to the short tires after having the taller ones.But I was really glad to have them on standby when the knots developed and I was waiting for the XTR's to come in. I had the XTRs put on my old polished rims. My original Kubota rims are12" . So I ordered 27"talland the width I wanted to fit a 12 " rim. I wanted 9"width in front to avoid rubbing and 11" in the rear.I have 1765 Hrs on my RTV {Hoss} and just love it and these tires make it even better.Ask any questions you like and good luck deciding[&][&]!
