-Usually the rear tires will not be felt as you are driving down the road.
-Front tires with stiffer sidewalls, can be felt as you go down the road.
-We found the first set of 6-7 year old OEM Toyo's were both loud, and firm riding. (No idea how the 1st owner took care of the tires, and we were replacing them due to age anyways.)
-The set of Michelin XZE*'s tires, have extra meat on the sidewall to protect agains curb kissing opportunities. Always felt safe, not bad on noise, but were even stiffer riding on the front end then the Toyo's. (Expansion joints, DOT's between the lanes, etc.)
-We had to replace 2 out our 8 XZE*'s at age 5, due to a pot hole encounter that broke a cord in one tire, and slipped a cord in the other. (Very good chance, that a less robust tire - would have had a blow out by this impact. So, I felt the XZE*'s gave me a safety edge - but paid for this in price, more stiff front end ride, and less MPG due to higher rolling resistance.)
-Tire shortage at the time. So ended up with 2 BF Goodrich ST230's, and put those new tires on the front/steers. They rode well, less stiff and you could tell the difference in a softer front end ride.
-We replace the other 6 XZE*'s earlier this year. Went with the Micheling XZA2. Put the ST230's on the tag. The XZA2's ride softer and quieter then the ST230's. Pleased with the choice, and they have less rolling resistance then any other others mentioned, so may yield slight increase in MPG over the years of usage.
Other tires that I was told by other DP's owners that I know, and respect, that provide good ride at a bit lower cost point - were the Hankook AH12 or AH11 depending upon the size you need. I for sure, would not have been concerned with putting them on the rear. So one option is Hankook on the rear, and Michelin on the Steers. (Save some money.) Or, Hankook all around - as again, I trust the feedback of the DP owners that told me to check them out...
So, their is my input
Best of luck to you,
