Yes, and I have heard stories about folks with retractables and those retreads getting stuck in the wheel wells.....YIKES
GAWD! No thank you! Uh huh! No way am I installing retreads on our 150. I couldn't stand the tension every time that I flew worrying about if my gear was going to come down or not!!

Seriously. The Dresser 600-6 retread costs $65. Add $12 for shipping and we have $77 each. Looking at my Chief catalog, Airtrac tires are $68 and are shipped free. Why would I even consider putting on retreads?
