I have R4 tires on my B2910 and in mud they fill up and basically become slicks. I thought the R14 would be a great compromise.
Then I watched a Messicks video featuring R14 tires. And it looks like there is a lot less meat there than R4s, to the extent that my impression was they would wear out quicker than R1 tires (even if wear is not really a concern for the most part, not running on pavement).
So now I am thinking if I were to buy a new L2501 I would probably go with R4 tires. The 15" width might perform better than the 12.4" width R4 tires on my B2910 I suppose. And they just look more robust than the R14s...
Am I misguided in thinking this way?
