305/55R20 General Grabber A/TX on an AT4 review

[calgator73]

Ride quality...pretty good.  Takes lots of weight to balance these and it's still not perfect.

Road noise....fairly minimal all the way up to 80.

Fitment...very slight rub on the factory splash guard at full lock to the left when in reverse....but no issues full lock on the right.

Fuel economy.....this will leave a mark.  Normally about 21mpg at 77.   Took a trip to Florida on I-95.  Averaged 15.4 mpg at 77.

Are they LT or P rated?

 

I can see the LT's really causing that hit to fuel mileage and the extra weight/width of the tire.

LT and E rated

Kinda what I figured. Pretty much overkill for a half ton and why you found out what you did.

 

Decent tires though.

E rated tires will kill your MPG, they sure killed mine but I'm running 34's, so it's even worse.

I might try jumping my tire pressures.  I'm at 40 all the way around right now.
