| Post subject: | Replacement tires dilemma--Load Ratings and other things |
Am needing to replace some 255/70/16 Scorpions that are on my '02 Liberty LTD. Was looking to go to General Grabber AT2s--but I'm noticing the higher load rating (E) is only available in 245/75/16s in this tire. Really unsure about the difference between the AT2s vs. the Scorpions as it is in terms of rubbing, etc. in the same size I have (the Scorpions don't really rub right now) -- plus I'd like to not have to buy 5 tires (ideally would prefer to move one of my existing 255/70s to the spare). Is there going to be a big performance hit if I go with the lower load rating? This vehicle is mostly used on the road but I want it to remain reasonably capable offroad as well. Thanks. |

as long as they are at least as high (just under 2000#s I think) you will be fine...but with a heavy vehicle like the KJ, I try to get the biggest load rating I can get for the size...D Rating will also be an upgrade |

It looks like the 255/70/16s in the AT2 have a load index of 111, or 2,403 lbs. The 245/75/16s have a load index of 120/116S (unsure why there's 2 numbers) which in lbs would equate to 3,086/2,756 lbs (I guess--again, unsure why there's 2 numbers). I can't find or understand how to calculate a Load Rating letter for the 255/70/16s--they specially call out that the 245/75/16s have a rating of "E" on Tire Rack. |
