Wheels & Tires
 

What are the widest rear tires and wheels that will fit on a 69 Mach1 without tubbs or modifying suspension? All help appreciated.:)

i have the same setup of wheels on my 66 coupe, 15-7 on front and 15-8 on back. i talked with a goodyear store owner yesterday and he suggested 235-60r15 for back and 205-65r15 for the front,,,,but the best thing to do is look at their catalog and it will give tire width and height in (normal terms), this will give you a good idea of what you can stuff into those wheel wells.

I have 15 x8 with 275 50 drag radials on my 69. so i know u can go that big. I wouldn't got any bigger than 275 though. Mine seem to just fit. there is someone on here that has like 300 something on his 70 mustang though.

yeah the 235's fit realy good. i have them on my 66. never had a problem with them and they look good too... they dont look too big or too small for the car.

I run 15 X 7 with 225/60R15 all the way around on my 68 Fastback.

Only time I have a problem is when I hit BIG dips and front wheels are turned. They will drag alittle.
