Walmart Black Friday: Goodyear Wrangler ST P225/75R16 Tires $79.00

Can I install these on my van? I have 225/65 r16???

Not really because speed and odometer readings will be inacurate. Follow your manufacturer tire size recommendation.

How will that odometer be off?
If both tires are r16: r= radius, that's the important part!

Radius is for rim. 75 tire has higher sidewall which means that 75 tire has larger circumference than 65 tire. Speed reading will be lower than actual. The same will apply to odometer reading.

Hope this works...copied from THIS SITE. [miata.net] (Very useful for "car guys")
Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
225/65-16.........5.8in.....13.8in....27.5in.........86.4in...........733...........0.0%
225/75-16.........6.6in.....14.6in....29.3in.........92.0in...........689...........6.4%

6.4% difference @ 65 mph is 4.16 mph. If the speedo says 65 mph...you are really doing 69.16 mph!!

Savings aren't worth the speeding ticket.

Roughly 2 inches taller than stock. (like adding a 1 inch thick layer to your original tire size.)

HERE [rimsntires.com] is another AWESOME tire/rim calculator! (Way more in-depth.)

Hope this helps.

I plan on trying to get the 17" wranglers for $99 each.
