I'm looking at a truck with 20" Fuel rims and Toyo 305/55/20 on it. For those who run a similar setup, what ride quality and fuel mileage can I expect? I haven't had time to do a test drive yet.

Stiffer than stock ride, not bad at all relatively speaking..very subjective.

 

Avg 14.7 last 400miles

 

Can smidge 17.5 on a warm sunny day at 61mph.

Around town drops to 11mpg or so.

 

In my instance I noticed a ~3 mpg loss from stock<>level/33"mt/valance delete

Thanks for the replies. It has a dealer installed ProComp 2.25" level on the front only and 3.42 rear end. The dealer is almost two hours away so I wanted to get an idea of what to expect to hep me decide if I should make the drive.

305/55/20lt nitto trail grapps on xd wheels. Was running around 14-16, but my speedo was off 4 mph at 80. Just installed a Diablo tuner at week to correct the speedo, now I'm running around 16-18. 3.42 6.2 I say go drive it. I use my truck for a work truck, on and off road. love the look of truck tires, not car tires on it.

Junk is right on with the 3 mpg loss, I'm slowly getting the back with a tuer, k&n filter, doing homework on exhaust, or drive about 30,000 miles a year.

I have 33" x 12.50 Load Range E tires and 3-4 mpg loss is about average for my setup.

Agree with everyone, went to up 2" and then to 275/70/18 E-Load DuraTracs- On the highway I average 15/16 and don't even ask about around town (NYC)....

With the above setup, I took a road trip 1000 miles and got 16+, maybe 17 actual with a correction for speedo error. Drove 75-80 mph on highway and 60-70 miles of dirt roads. Still, the average for the entire time I've had the tires is 14.4 on the DIC. That's probably 15 corrected. That includes going to work which has 10-15 miles of freeway each way, depending on my path and the rest has been mostly city.

295/55r20 Toyo AT2 Xtreme on Stock 20's, RC 2/5" Lift/Level.

I haven't re-calibrated my speedo so the mileage should actually be a little better than what's displayed... I average 80% highway 20% city driving.

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65

      Factory front brake rotors...defect?

      By Chris80s · Posted

      On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.
