Hey everyone....I just got a new white G coupe, and I want to put 20 inch flat black wheels. I have a couple questions before i do it.

-Do the 20s slow you down and waste more gas?
-can you put an all season tire on there, or can only a high performance tire fit?
-any rubbing issues?

I could always do 19s but want BIGGER!



Thanks

1) Yes 20s do slow you down , there usually heavy.
2) all season tires would work, I'm sure some tire company makes all season 20 inch tires
3)no rubbing issues with stock suspension , and no rubbing issues with lowering springs or coilovers depending how low you go

 

Thanks for the quick response. Looking at the Rohana RC5 wheels. Look sweet.

 

I'm on a sedan but as far as your concerns~
-Do the 20s slow you down and waste more gas? A little bit, but IME, not much. I still can get about 29 hwy w/ my 20s and I've got pretty big tires out back (295/30/20)
-can you put an all season tire on there, or can only a high performance tire fit? I have Toyo Proxes Plus 4 All Seasons on mine, great tire, nice treadwear & speed rating and also great prices on our site vendor Treadepot, here's a couple links, one for a review of the tires and another for the Treadepot link, ask for Andrew & mention myG37 for an even better price Plenty of All-Seasons in 20" size to choose from BTW.

-any rubbing issues?
Unless you go crazy wide, or a diameter that's too tall you'll have no issues. Keep in mind that you really want to be within +/- 3% of your OEM diameter. Use this calculator to determine what's best~

FWIW 245/35/20 is a good starting size as these are right on OEM diameter specs, then if you want to go wider just use the calculator.

Those Rohanna wheels look nice. I'm really happy w/ my Nutek Bavaria flat black 5 spokes, got them from GOTO racing.
Here's the Nutek low pressure cast line (about the same price range as the Rohannas) if you're interested~Most of the wheels are available in flat black & plenty of offsets.

Here's a pic

 

20's won't slow you down if you get them lightweight 2 or 3 piece wheels.

 

Thanks guys! Great info. The 20in package does have the Toyo Proxes Plus 4 as an option. Ordering this week.

 

Post some pics in this thread when you get them on, should look great!

 

Sure will do!!!! Thanks for your help.

 

Are there any issues with tire pressure sensors on aftermarket wheels? And.... Any camber issues I have to worry about?

 

Most of the newer wheels will accept the TPMS sensors no problem. There's a DIY thread about resetting your sensors in the DIY section, most places like Discount tire can do it for you but the DIY seems pretty simple.
Your alignment settings won't change w/ new wheels, only when you lower (or raise) the suspension, or alter something else w/ the suspension.

 

So I have vossen cv2 20x 10 +55 all around do you think I'll have any problems. I have g37xS sedan w/ stock suspension

 

Do you already have them installed? You'll be OK as far as fit at the fender (depending on what tire size you're running) but the inner clearance at the upper part of the steering knuckle may be an issue w/ the wider wheels and high positive offset.

 

I have 255/35 tires

 

Do you already have these on the vehicle? If so might want to check your clearance at the steering knuckle. Luckily running stretched your tires shouldn't be a factor.

 

No but I'm going to test fit once I get some time. Once I do I'll let you know how it goes I Was just seeing if anyone else has run that high of A offset With any problems
