I guess that depends on how much money you have to spend. I currently have some Yokohama Geolander A/T-S LT235/75-R15 tires on my T-100 at the moment. Been doing fine since 2 years ago...not sure I'd go with anything else as it's been working just fine fer me.
You should be able to git the tire patched again...it might even be under warranty since patch repair work isn't supposed to leak. What's the manufacturer date code on the tire? I would use that as one of the indicators in replacing a tire...besides wear or balance.
