How much does tire and wheel weight effect MPG?

[gumby79]

Most "H" or fasters speed rated tires eather have no load capacity or are 28" or smaller or10-30"wide drag rears.

To day I've found some options

32.18"D 235/55r22 (104w) 1984lbs 168mph $154 usd


31.41"D 275/25r26 (98w) 1653lbs 168mph $215 sud


30.04"D 255/50R20 (109Y) 2271lbs 186mp

There is also a 32.68"D 315/35R24 w
Stock 31.7"D 235/85R16 LT S speed rating. Yielded 87.14mph 1:03279 standing mile.
What kind of impact should I expect ?
Going to a smaller speed rated tire requires installing a Bonneville specific quick change rearend for gear, just to get to 130mph @2500 RPM.

No.

Coroplast is cheap and impermanent. If you want cheap get Moon disks and zip-tie them on. To do justice to what you have, there is a particular JDM wheel that was a spoke wheels with a dished cap that fit into between the spokes as an aerodynamic upgrade. If I remember what it's called I'll come back and edit this. You could make something similar by indexing a cap and cutting 15 notches in the rim.

Else, a center cap with left/right handed knock-offs that just hold the disk.

The real question is, why not? How important are aesthetics to you?

Those look like the backs.

I was just kidding really. Only on ecomodder's do you take a nice new set of alloy wheels and cover them with cheap black plastic, even if they did cost next to nothing. That being said, no I don't really care about aesthetics and I might still cover them up.

Hahaha! FWIW, I would not cover such rims with cheap plastic. I would sell them and buy crappy rims & good LRR tires!
