Weight penalty with meaty wheel look

[2Wavy]

I weighed my wheels and tires unmounted and added them up, and got 40.4 lbs. I think after wheel weights and tpms sensors and being filled with air, they'd probably be around 41 lbs. I have 17x9+35 RPF1s and 245/40/17 Dunlop Direzza ZII Star Specs. I could have cut a little bit more weight if I had gone with RE71Rs I think.

These wheels were around 1200 for a set of 4, and each wheel weighed 15.6 lbs. I don't think you can do much better in terms of weight unless you step up to a much more expensive forged wheel.

If you want a lighter wheel, that still looks decent, check out the PF01. It's only 18.25 lbs in 18x8.5.

I agree the RPF1s do look a little dinky and the PF01 is a good looking wheel. Maybe I'll buy them as my summer wheels and keep the Raijins as my winter wheels.

I have been looking at Forged XXR 527F 18x9 +35 wheels @ 18lb each.




IMO, Sexy and fairly light.

They also have a 18x10 +40 @ 20.2lbs

However, wheels are highly individual and subjective, and I would still want to fill out the wheelarch. I really don't like the tiny wheel look. Having said that, I checked out tire rack for tire weights and used a Michelin Pilot Sport 4S for this comparison. I specced it in 225/40/18 and got 21 lb. Then changed it to 245/45/17 (sufficiently meaty?) and got 24 lb. That would almost negate the weight savings. Are people aware of this? Are these weights provided by tire rack correct? Cause that would take a 5 lb per corner advantage and cut it down to 2 lb...

Are you comparing a 225/18 setup to a 245/17 setup based only on weight? The reason for a wider wheel and tire is to provide more mechanical grip (all else being equal) for cornering. If you don't care about cornering and you only care about looks, then why would you care about weight in the first place? I think this one just comes down to whatever you care about the most, but if we're talking performance around a track, 17's are generally known to have the advantage.

It's a combination of surprise on my part at discovering that light 17s with a fat tire weigh almost as much as not-so-light-but-not-heavy 18s with a skinny tire, and wanting to have the same overall diameter. Cause my winters were OEM wheels with a 215 section winter tire that isn't meaty at all, so I could feel the difference in overall diameter. I want to maintain consistency and not have to get used to something new every winter/spring, so I thought with a light 17 wheel and a meaty tire I could maintain the same overall diameter. But if the weight is gonna be almost as much as an 18 anyway, there is no point. Gonna buy another set of 18s and call it a day.

Personally I don't care so much about wheel weights for a street car. Yeah, don't want anything that is super heavy, but used to have XXR 530's, and now have a set of XXR 527's, both cast, both 18's. Swapped stock rims and these and honestly don't notice much difference in acceleration in street driving. Ideally, get a light set of 17" x 8" rims, throw on some good track rubber 225 width and use those for track days. They can be ugly, they can be cheap, they can have road rash etc. Then get a nice set of 17" or 18" rims for the street, with wider tires and correct offsets to fill the wheel wells, don't worry too much about weight. Especially if you're adding an Edelbrock SC. my 2c

As for going to 17x7-17x8 wheels, would that be sufficiently wide if I went FI, or does that depend solely on the tires?

lol no. I run a 255/35 RS4 (265 would be exactly square) on a 18x9.5 wheel and I still break traction upon acceleration if I wanted to and I'm at about 350whp.

If I were you I would get 17x9 with some stick tires, get a 255/40 for max grip. If you want a slightly stretched look get a 245/40.

17x8 is an NA autox setup imo.

Are you turbo'd or sc'd?

Unless you track, stick with 17x7 wheels and 215, with a light wheel and keep the car playful.

No one will confuse your car with big wide tires with a Porsche.

If only going for looks, it’s your car do what you want, it’s all good.

I admit those meaty tire threads always look cool.

17x7? nah, even if you stick to 215 width tires, a 17x8 will accomadate the range in width available for 215 tires better, especially if you choose utqg lower than 200. Which tend to run wider.

Two companies that make lightweight wheels & tires at good prices:

-Look at Konig Flowformed wheels
-Tires look at Hankook Ventus Evo ii's

I wasn't sure by your post if you wanted to stay 18's or 17
245/35/18's wider and the right outside diameter at 22lbs https://www.tirerack.com/tires/tires...omCompare1=yes
245/40/17's are actually a pound heavier at 23lbs

I went with stock size 215/45/17 and got 19lbs on my scales so tirerack #'s are right

Also went with konig Hypergrams listed at 16.3lbs I got ~16.5lbs so their weights are correct as well. They don't look they great as they look small but they have a few new styles.

I like their new Dekagram wheels you can get a 17x9 at 17.3lbs
or at 18 x9.5 with concave face at 19.8lbs

Thanks! Yeah when it's time to replace the MPSS, I'll pay closer attention to tire weights. I might get the Konigs as winter wheels. They're fairly priced. Don't think I'll be going down to 17s. I want to maintain the same overall diameter, which means heavier tires and it's no longer worth it.

I replaced MPSS with hankook evo v12. I wish I had just got another set of michelins. I do not like them. They have a soft side wall, squeel eaisly, and squirm on corners compared to MPSS.

if I ever decide to go forced induction those would be at the top of my list Staggered!
