I have an '03 that was purchased on 12/31/02 & has the leather wrapped wheel. I live in Phoenix, AZ. (desert conditions) & the truck has to be parked outside at all times. Since day one, I have covered the steering wheel with a cover made of the same material used to make dash covers & I use it whenever the truck is not being driven. The windows are tinted, also.
I, regularly, apply Obenauf's Heavy Duty Leather Preservative to the wheel that I got from White's Boots in Spokane, WA. White's makes custom, hand-made boots & recommends the Obenauf's for leather treatment. Seriously, I don't know what else to do to extend the live expectancy of the leather cover.
Not long after purchasing the truck, the outer skin of the leather cover started coming/peeling off exposing a textured leather that looks like the cover of a football. It's mostly in the area where my hands contact the wheel. I wonder if I have more acids in my skin than others? Not sure if that's the problem, or not.
My '91. 5 W-250, which, I purchased new in 8/91 has the vinyl/plastic wheel & it still looks good with 183,000 miles on it & not one day in the garage. It gets covered, also, when not in use. I doubt the '03's wheel will last nearly as long judging from the way it looks now. Sure wish I had the plastic wheel in the '03!!!!!
What is the advantage of the leather wheel, anyway? Seems to me that it is just something more to prematurely wear out. I worry about the longevity of this wheel everytime I look at it. Never did that with the '91's wheel.
