Is it possible?

Ever since I got my new wheels and tires it feels as if my truck is faster. Is this possible? I got 265/75/16 tires. Before when I would go past those radar things the cop set out my speed was off by like 3-4 miles per hour. Now when I go past it is dead on with what the speedo says. It seems like the tire size could have actually corrected my speedo? I swear my truck feels like it is faster but that could be to lower weight of the tires maybe?

Did you get the exact same tire size when you got new ones?

I went from 245/65/17 to 265/75/16. I have the axle gears that everyone swaps out (not the good ones the xterra and frontier have). I swear that like my gearing was off with my stock tires and when I got the bigger tires they some how corrected the gearing.

bump?

So you went from the equivalent of a 29.5 x 9.5 x 17 to a 31.5 x 10.5 x 16. Plus the new tread depth compared to the old worn out tires. (some tires have more tread depth than others)

 

Gain: 2" tire height and 1" width. +6.67% larger tire compared to the old set.

Loss: -7.15% speedo reading, -47 engine RPM per mile.

 

What size tires did the Pathy have when new? I wonder if there were several optional sizes.

Also, what did you have on and what are your replacements ? Tread pattern can make a huge difference to how the car feels and responds.
