Silver, that doesn't make any sense. The transmission would only think you were driving 4% slower than you were before. The effect would be no different than if you were driving faster or slower.
BTW, I'm running 225/70R16 on my XL7 with no issues. The slighty thinner tires cut through snow and slush better and allowed me to choose much higher rated tires (per Tire Rack) than available in the factory size.
look the only way you may damage the tranny is if you ran say 3 235/60/16 and one 235/70/16 for a long period of time.Jonesy you are right the tranny would just think you were driving slower say 56 instead of 60 no big deal at all,i went thru this already when i changed my tires to 225/70/16 (stupid tire salesman)no issues at all ,there are even people running 32" tires with no problem except for the super slow pickup.lol.
I'd be more concerned about my driveshafts and perhaps diffs when fitting bigger tyres. They're items proven in most 4WD models to fail first when a lot larger tyres are combined with aggressive off road driving.
BTW acceleration will be slower and the brakes won't be as effective.
So what you are saying is if I drive slower by 4 klicks everything will be alright with the tranny . The tranny drives the wheels period. the revs are for your speedo period. If one was really worried about the speedo being off you would get it recalibrated. And that has nothing to do with the performance or operation of the tranny. It`s just a signal or a regeared cable that needs to be changed.
completely untrue... 100% untrue. Sorry silver. I have no idea where you heard that from but its a bad source. As long as all 4 tires are the same size the trans and transfer case don't care at all.
I surely don't want people here to think that they can do damage by not running the same as OEM sized tires..
cause that won't happen

This can occur because the transmission is set up for the OE tire diameter and increasing the overall tire diameter will not only give a false speed indication, it can also lead to transmission failure.
