I hope to prevent someone from making the mistake I did. I wanted a long wearing stiff sidewall tire (hoping to lessen roll in corners and uneven wear) that would be good in snow and mud and work well under heavy load with my 2 91 AWD Aerostars. All terrain light truck tires seemed like a good idea so I got Cooper Discoverer A/T 225/70-14 . Big mistake. They are no better in snow than the bald passenger tires they replaced. I credit the E4WD for making the most out of any tire. They are very noisy and cause a 'swaying' feeling while making small corrections during highway driving. The ride is harsh, all bumps are felt and heard in the aging suspension. I could live with that if it didn't accelerate wear on the suspension and cause the cheap interior panels to rattle and crack in the cold. The slightly larger diameter and heavier tires cause a noticable loss of power and slightly worse gas milage. The reduced contact area due to large channels between tread blocks causes it to skid much sooner on icy roads. And when it does, it leaves alot of rubber behind. So basically, on the Aerostar they are worse in every way imaginable. Odd because on my Chevy truck they work quite well. That is why I chose them. So I recommend sticking with passenger tires or light truck highway tires. The wider 225 section tire does not rub anything and it does look better, so I think it would be satisfactory in a lighter weight tire with less aggressive tread. Just watch your air pressure on those narrow rims. A little lower than usual but don't let it get too low.

 

Ranger 15inch rims have the same bolt pattern and offset as the stock Aerostar rims. Run 215/65 15's and the diameter is the same as the stock 215/70 14's. Get the Ranger rims that are 6 inches wide, not the ones that are 5.5 inches.
