I didn't get any pictures because I was working, but had a TRX running 28" drag radials in the factory wheels at drag strip last Saturday. Looks equally as stupid
I will say anecdotally that I swapped in 22's on my Bighorn from the factory 20's, and my MPG has dropped. 1-2mpg estimated in both city/hwy. Both tires using road-focused all seasons, too. My 20's were still on the factory Bridgestone Duelers (pretty good tires IMO), new 22's are on Pirelli Scorpion WeatherActive XL's, which i've no experience with personally, but were 'best in category' on Tirerack.I really don't understand something. So the 22s...
-more wind resistance
-more weight
However they also
-turn faster (circumference) than smaller tires bringing engine RPM down at a given speed
Do they help or hurt mpg?
Yea, but at the strip when racing is actually functional. That blue monstrosity is just dumb. But...as with anything, if the person who paid for it earned the money in a legitimate way, I'm all for people spending however much they want on what they want. I blow money on plenty of stuff that some people think is dumb.I didn't get any pictures because I was working, but had a TRX running 28" drag radials in the factory wheels at drag strip last Saturday.

LOL... quick question... what gear ratio do you have?I will say anecdotally that I swapped in 22's on my Bighorn from the factory 20's, and my MPG has dropped. 1-2mpg estimated in both city/hwy.

Others have mentioned the circumference thing - but generally "wheel" is heavier than "tire", so the jump from 20 to 22" wheel will increase the weight:
apples to apples, for example:
My new tires in 285-45R22 - 39lbs
Same new tires in old size - 275-55R20 - 40lbs
wheels..
My old wheels - factory night edition 20's - 33lbs
New wheels are OEM replicas off TR in 22 - 40.5lbs
Assuming I kept the same tires (which I didn't, but it's the best way to illustrate it, because as others mentioned the tire design etc definitely factors in considerably) - by going from 20s to 22's, I've added ~6lbs of unsprung weight to each corner, which bounces around over bumps, spins fast, has to be accelerated, braked/slowed, and accelerated over and over.
Conceivably, it is possible that with a light enough larger circumference wheel you may reach parity between the two? But you might end up with wagon wheel looking setup which might.. say.. otherwise compromise important handling characteristics.
Yeah, but the guy who had it still couldn't drive and his times absolutely sucked.Yea, but at the strip when racing is actually functional. That blue monstrosity is just dumb.

Lord that is bad.whoever did that should be flogged.

Yep, I was going to say the same. I believe my 35 inch tires weigh more than my 18 inch aluminum wheel.That only applies to some of the 32" SL tires. When you move up to an LT tire, 33" or bigger, or a tire that fits an 18" wheel, the tires weight quite a bit more than the wheels.

I have 3.92's.. no dice there! but the circumference between my old tire setup and my new is either identical or nearly so, so it's only the weight difference in my case. Both are factory sizing so I didn't have to change the speedometer.LOL... quick question... what gear ratio do you have?
My thought process is that with 3.92 it could offset fuel consumption due to higher RPMs on the freeway... bigger diameter tires should slightly drop RPMs.
Right, that's very true. I destroyed my old trucks MPG via switching to some LT KO2's. Was brutal, went from 17-18hwy to 13-14. Looked great though!That only applies to some of the 32" SL tires.

Also road smoothness and wind.Tire sizes, tread pattern, and air pressure, along with circumference, all play a role in mpg. Also, the narrower a tire and the weight of the tire, play a part. So, a narrow, bias ply, with highway tread, max inflation, and stock tire height, and driving with an egg under your foot, will maximize mpg. Just the way it is. But hey, it's a free world, and we can all eat at Burger King.
And apparently temperature and humidity. Tread pattern. Driving on concrete vs asphalt. Elevation. A swarm of cicadas might be a challenge.Also road smoothness and wind.
Yes, but environmental variables are much harder to control.Also road smoothness and wind.
Ive started using fuelly also. Only have the last 4 fillups logged. How are you getting the accurate city/highway pie graph ? Do you enter that data yourself ?Been tracking for awhile and just as I expected.

Surprisingly after changing from 32” tires to 34.3” my gas mileage stayed virtually the same.
Exactly. So we may never know if 89 gets better than 87. Too many variables.Yes, but environmental variables are much harder to control.
Yes. Just taking a guess. I don’t really do any actual stop/go big city driving like many do. Mostly passing thru small towns and country driving. I think a 60/40 mix is likely pretty accurate.Ive started using fuelly also. Only have the last 4 fillups logged. How are you getting the accurate city/highway pie graph ?
