    Hey guys, first time posting but have been a frequent reader. So much helpful information on here. Wondering if I could get some input on my setup.

    Looking to go to 33’s from stock but was really wanting to avoid sacrificing ride and what little mileage I get by going 10-20lbs heavier than stock with an lt tire. I have stock 18” trd wheels and am seeing not many choices for 33’s in SL tires. It does look like if I swapped out for some 20’s I could get a 275/60/20 in SL’s and just add approx 10 lbs per corner as opposed to 15-20lbs per corner with 275/70/18’s in LT tires. My question is, since the assumption is with 18’s I’m already getting a softer ride, would the ride compromise with LT’s be negligible? How about MPG’s? I get about 13 normally around town and 17-18 on extended highway trips. I’ve never run an LT tire before so not sure what to expect in compromises to power and mpg and will only tow/haul anything substantial probably <6x per year. Any advice or personal experience is appreciated.

    Going to a 275/70/18, you likely won't see a noticeable difference in power. For the MPG, I would say bank on a 1 mpg loss. I personally wouldn't swap out the 18's for 20's, just to get a tire that is not an LT. I doubt you would even see much of a difference in mpg honestly between the 275/70/18 in an LT and the 275/60/20 SL's.

    What type of tires are you looking to run? Wanting still a hwy tire, AT's, etc?

    Thinking if I went LT probably the cooper discoverer at3 xlt...it’s about 13lbs heavier per tire than stock I believe.

    Alot of them
    Going to the 275/70/18 you are only going about an inch bigger. The stock tire is around a 32.1. I definitely wouldn't go to a 20. Going from an 18 to a 20 will kill your mpg.

    Unsprung weight is huge for mpg and performance. 10lb per corner is 40lb all together. rule of thumb 1lb of unsprung weight is about 10lb dry weight in the bed but it could vary. So typically you will be gaining 300-400 more pounds in the truck just switching tires. Now remember its where the weight is on the hub. If its closer to the hub its not that drastic. Tires will play a bigger role than wheels do as for unsprung weight because most of the weight is away from the hub as oppose to wheels. Now im not saying go with 20s it all depends what you do. If go offroad alot or crawling thats needed for the extra sidewall. 18" will be lighter than 20" which does matter and they will ride nicer because of the extra rubber and typically same size tires for 20" or 18" will weight the same. You could do 275/65 r18 nitto terra g2 on some 18x10 -18 ish. It will stick out but it will give the wide stance for aggressive look at the same time you will not gain any weight. G2 are 44 pounds and 18" can get down to the 28. I think moto metal 18x10 are 28 pounds.

    None yet.
    I am running Falken Wildpeak A/T LT295/70 R18 (Load Rating E) on stock 18" TRD rims. Could not be happier with the tires, very quiet and smooth on pavement and highly capable in snow and dirt. Have a 3 1/2" Rough Country lift and had to remove front mud flaps and trim skid plate 2" on each side (didn't want to use spacers). Averaging about 16MPG driving mostly around town (we have no freeways where I live).

    275/70/18 on stock suspension works and looks great. LT tires will reduce MPG a little and the ride is going to be a little stiffer....but you can chalk test the tires and experiment with air pressure to get the best ride with a good contact patch.

    Ill be installing that size on my stock Crewmax when it is time to replace tires....for sure!

    Looks great! Interested to hear how they ride as you get more miles on them.
