Wheels and tires Please

Okay, I'm new here. Not sure if I could have just searched for info. I have an 08 Taco USED with 18 inch XD's (not sure part number or offset) on Nitto Terra Grapplers 305/60R18's. These wheels weigh about 38 lbs and am getting like 12 mpg... I would like to go smaller/lighter like 17's and tires but not sure what a good setup would be. What are y'all running and what MPG y'all getting? I just don't really want to spend $1500 on new set of tires if I could get new wheels and tires for less and improve MPG. I would like to still have all terrain tires. Thanks.

 

38 lbs doesn't seem right. The tiny factory tires that came on my truck were in the mid 30's, I don't recall exactly. The LT 265/75/16's on there now are ~54-56 lbs. Once again I can't recall exactly and don't want to look it up.

The tires you have are 32.5" tall and 12" wide. The width is really increasing rolling resistance and you're 2" taller than stock which does a couple of things. #1 it makes your engine work harder, and it changes the axle ratio giving you less power. It is also messing up your speedometer and odometer. Both are off by about 6%. If your speedometer says 70, you're actually doing 74. If your odometer says you drove 200 miles you really drove 212. Unless you've already calculated for that your fuel mileage is actually a tiny bit better. Around 1/2 mpg.

If the wheels you have are not too wide you could go to a 265/60/18 and get almost exactly the same overall height and width of a stock tire, about 30.6" tall and 10.5" wide. A 265/65/18 would be a good compromise splitting the difference in height, but at only 10.5" wide will really help with fuel mileage.

This way you can use the same wheels and save a lot of money. This should work, those sizes recommend a 7.5" to 9.5" wheel. Unless your wheels are over 9.5" you can still use them.

I have LT265/75/16's on my truck. That is a 31.5" tire that weighs 55ish lbs and I still get 16-17 for everyday driving and 19mpg hwy. Stay with something with a moderate All Terrain tread similar to what you have and I think you'll be fine. It is the aggressive mud tires that kill fuel mileage.

 

Thank you for replying. The weight was of the wheels not tires. The wheels picture is below but I do not know which of them they are. I haven't looked up.

Okay so this is what google said on tires.
305/60R18 116S XL BSW 32.4" 54.2 lbs

I am sure truck has a lift but not sure how much. I don't want it to look stupid if I drop size of tire and wheels without taking off lift but I do want less weight. I have found some wheels that are 26 lbs each which is a big difference. Trying to examine my options.

That will be nice if I can get those on the wheels. Guess I just need to take to a tire shop and ask them to see. I don't mind look of wheels just know I don't want to spend money on same tires.

True, I don't want something crazy mud tires. I don't go off road but I plan on a little bit. Not mudding though.

Thank you.

 

he said wheels, not tires (or thankfully rims).

tires should be about 55lbs each.

I also have 265/75r16, and get 17mpg. Lift is about 2" up front and 1" rear

 

My American racing wheels were about 25lbs each and they were $115 each. Highly recommened. Any of the big name brand ATs are great these days. If you're not too picky just go with the best deal you can find. I would go with 265/75-R16 or 265/70-R17 depending on the wheel you end up with.

Not sure where you live, but here in SoCal craigslist/offerup is full off stock takeoffs and other wheel tire combos. You can get a full set mounted for $400-$500.

 

i noticed moving from GoodYear Duratracs to Falkes Wildpeak ATW3s my mileage was considerably better. ride was quieter but i get 60more KM per tank now. my setup is KMC Enduro 17" and Falken WildPeak ATW3 265/65/17, i also ran PSI at 34. found the stock recommended 29 to soft and bouncy.

 

How long have you had this truck? I would clean the throttle body and mass air flow sensor. Put a new air filter in also and change your plugs. And to your question im running 265/65/17 goodyear duratracs with procomp wheels and i get an average of 18-20 mpg

 

Its those XD wheels. My buddy has basically the same setup on his f-150 and they're heavy af.

Look for some OEM 16-17 inch wheels for sale, any 2nd or 3rd gen style will do. I see 2nd gen take-offs with tires for cheap on CL all day long. Like $100-200 (set of 4) with tires ready to go. They fit great and don't weigh a ton, you can get bigger tires if you like and still come out lighter than those XD clydesdales
