The 36" radials are a decent tire. Just wait till you get another set of swampers,they will eat those radials for lunch! On the datsun I had in HS i bought a set of 32x10.5 tsl radials, at the same time a buddy bought 36x12.5 radials and mine were the same pattern and lug size as bias tsl's. The 36" have smaller lugs and tighter spacing. The 33" radials are the worst the lugs damned near touch!
