I got these installed yesterday

 

What size and specs? They look really sexy!

 

They are Enkei Vulcan 17x7.5 and Yokohama Avid Ascend LX 215 45 17.

 

Looks nice and Enkei make good quality wheels, OEM for a lot of manufacturers.

Any idea on the weight of the Vulcan wheel? I don’t see any weight spec online.

 

They are 20.9 lbs

 

Wow that’s more than I wanted to do.

 

I was finally able to drive the last couple days. I’ve gone from 5k+ miles a month to <400 since March. I went on a 600 mile round trip Tues-Wed. The car feels much more in control on curves and at speed. I really like the way it feels. Fuel economy looks to be down about 10%.

 

@Rob43

What are 3 typical tire sizes for a 18" applications?

Also, what is your opinion on these specs on wheels/tires - 18x8.5 +45 (18.25lbs) / 225/40/18?

Thanks Rob

 

Rob43 asked me to report back on my 16" aftermarket wheel and tire setup (+1 as opposed to +2 17's), now that I've had a chance to drive it under various conditions, including a couple of longer highway jaunts. I bought aftermarket 16 x 6.5" wheels, 205/55 HR16 Michelin Pilot AS-3+ performance all-season tires (not Eco-rated), as well as a set of cloned pressure sensors.

I can say I'm very happy with this combination. I have a lot more grip compared with the hard, low-rolling-resistance factory tires, and I can take sweeping on-ramps and zip away from a stop quicker than before. At the same time, having more sidewall compared to a 17" tire means my ride quality and pothole resistance is still very good. I have not directly compared this setup to the factory one in efficiency, but my electric-only range does not seem to be affected significantly. I can still do my entire commute in EV mode, which was the goal. And tire noise is quite low with these Michelins.

As for looks, I always thought the 15" factory wheels were pretty puny looking, and the plastic covers cheapened the car's appearance. I love the wheels I got, but I think a set of 17's would look even better and could provide even more grip, but on average they will be heavier, louder, will clomp more over bumps, be more vulnerable to pothole damage and be less efficient. So it all depends on your priorities...
