Nice comparison chart. ThanksThe 170/80-15 will lower your rpm's over the gear range and look beefier. 180/70-15 will raise your rpm's just a little tad. Buy your tires to how much you travel a season/year. I never have used Shinko's but never heard any thing bad just longevity. Pirelli's was my bias ply tire of choice do to better mileage and no issues with handling.
160/80-R15 tires are 0.63 inches (16 mm) smaller in diameter than 170/80-R15 tires and the speedometer difference is 2.5%www.tacomaworld.com
Nice comparison chart. Thanks
Good to know. Another website talk about clearance problems on the front but didn't mention what tire brand. I like the look and price of the shinko tour masters. The 712 front sounds interesting.I run 110/90-19 Front and 170/80-15 Rear with zero issues.
