I am assuming these are the stock size? The real issue with the current tires is that they are pretty dry rotted. Im pretty sure the date on the one I checked said 1996!!
My daily driver is a 1991 Jeep Grand Wagoneer. It currently has a fairly new set of Kelley 235/75/15's put on by the PO. I want to upgrade the Wagoneer to an even larger set of BFG Radial TA's.
NOTE:
215/75/R15= 27.7" X 8.6"
235/75/R15= 28.9 X 9.3"
What do you think?

Thanks

The 235/75/15 tire works best on a 7" wide wheel, too narrow of a wheel will cause sidewall support issues and poor handling. The increase in diameter will raise the MPH some, but the speedometer will read slow compared to actual speed.

You sure the width would be an issue? For example, I run a 12.5" wide tire on a 8" wide wheel on my Jeep. This is very common in the 4x4 world. Think Im just gonna go ahead and do the swap.
