I went to the Tire Rack Tire Rack - Your performance experts for tires and wheels website and looked up tire size LT225/70 R19.5 and found that the overall diameter is 32". Then I keyed in LT235/85 R16 and found the overall diameter of that tire is 31.7". As I wrote in an earlier post above, the difference in size between these two common tires is 0.3" or 3/10". As I wrote, the difference is a fraction of an inch. That tiny fraction of an inch would not be noticeable for load starting ability and would make a difference of perhaps 30 rpm at highway cruise speed in top gear.

I will not bother to go do all the research to disprove everything you wrote, but I am confident that I could if I was willing to go to the trouble. I will just simply say I believe everything you wrote is wrong, incorrect, and I disagree with you.

This is a Dodge-Cummins website. You will have a very difficult time convincing TDR members of the merit of Furd diesels or trucks. Perhaps you are on the wrong website.

no mr barlow i'am not misinformed, not on the wrong site, and i'am not trying to convince anyone on the merits of ford or gm trucks for that matter. what i'am doing is provideing the facts. to a degree you are correct about the tires yourself. however my information is correct also, but perhaps should be clarrified. on average the 2 formentioned tires are very close as you say. there are however differences in the sizes of certain brands of tire and tread patterns, like i said earlier. example; the 235-85-16 bf goodrich tires on my ford dually are nearly 1" in shorter then the tires on my gmc 3500hd, which are 225-70-19.5 wanili's. this is even more common on big truck tires. as you say, is it enough to effect overall vehicle performance, likely not. as for other info, the proofs out there, look it up. i think you just dont want to know the truth, but then thats your buisness. however when you start preaching , how about preaching facts and quit trying to mislead people. point of fact, your comments about v8 diesel's with manual trannys cant even apply to many gasser trucks, regardless of brand. how many v8 diesel powered light ,medium and heavy duty trucks have you owned? auto or manual tranny equipped.
