    Hi Guys, wanted to do this here because all regions and altitudes will be different. What was your MPG difference from an OEM TRD Off Road/Sport vs. your new tire size, 265,285, etc. Hoping to hear from guys who drive the 5 and 405 freeway system with fairly mixed street and highway driving. Sorry if this has beaten to death. This is going to help me choose what size tire to go with on my new 3rd Gen TRDOR. Thank you for contributing.

    Tire size and gear ratio play a difference in a lot of areas, but dealing with traffic on the 405 or 5, fuck it, buy a Prius.

    Sh!+, any socal freeway is screwed if your in the city. Dude, Just buy a tire that'll stop you quick enough too not slam into the aholes car in front of you. I can't speak much for 3rd gens as I have the old pos best gen (2nd gen) but If you stick with a 265 P rated tire things shouldn't change much. You have an turdoffroad, so ill assume you have 16" wheels. 285's are more for looks not performance. Id Rock 265 75 r16. If you got and odd ball truck like me with 17"-265 70 r17 rember Any time you go wider or taller your adding rotational mass. More mass = less mpg. 285s will probably drop 1-2 mpg off your average depending on driving habbits. Im no 3rd gen expert, so don't shoot me if im wrong there but You kinda bought the wrong car if your worries are about mpg. I worry more about penguin sh!+ in the middle of the desert then mpg, just sayin...

    Thanks guys..not worried about the MPG's per say..just really wondering! I know I'm gonna take a loss, just gotta decide if I'm cool with 1-2 or 3-4 depending on size.

    If you go with a 10.5" wide tire as apposed to 11.5-13.5 then it won't hurt more than 1-2 mpg tops.

    I think you'll want some more detail. Plenty of guys roll around with an extra 500-1,000 lbs in stuff in the way of winches, bumpers, armor and bit hits in aerodynamics with RTT's, camper's, lights, big lifts, higher offset wheels, etc. You'll also want more specifics in tire, comparing a K02 in 265/60R17, just going from a C rated one to an E rated is a difference of 9 lbs PER TIRE along with less sidewall compliance. Don't forget driving habits, plenty of mellow trucks guys driving at the speed limit or 5 over, plenty of others tailgating every car in the left lane at all times regardless of speed.

    I drive a DD Scion TC for this reason, I did it for a week in the Tacoma and said no more. 30mpg on a DD beater is great... and having a 3year old Tacoma with barely 20k miles is pretty cool too haha.

    I'm running 285s on a 2005 sport 4door with a 6 foot bed. I'm not sure what the difference is from stock since it already had 285s when I got it. I did notice a hit when I went to a 5" lift in the front from 3". Also, the type of gas makes a difference too. I used to get 250 miles per tank comfortably before the gas light tuned on. That was pumping Chevron 91 octane but lately I'm lucky to get 200 with that same gas. For some reason Shell 91 octane has been getting me better results.

    Lets not forget brand and tread patterns of tires. I went from a 275/70/17 KO2s E rated to a 265/70/17 Nitto Ridge Grappler E rated. Dropped about 2-4 MPG.
