Would have had to go 305/20/22 to have an equal diameter to a 285/30/20. Does such a tire exist?

 

My setup is within 1% though...245/30 in the front and 285/25 in the rear. I did my homework on it for the AWD system

 

Wheels are actually pretty light, forged aluminum....I know they're lighter then any set of 22's i have owned on my last 3 cars. and you're right about the brakes...I hate that but I will look into getting the BBK for the car.....This G is my new toy so I'm kinda like a kid in a candy store looking at all these cool aftermarket parts for it, LOL....My last ride was an M45 and there was nothing for it, LOL. Big difference

 

I'm pretty sure the AWD diameter is the same as the RWD, which is 245/45/18. That would put you 3.5% too large which is quite a bit.

 

I don't know where you did the math, as you used an 18" tire as your basis but the circumference is -0.56 inches in difference, -0.18 inches in diameter and -0.08 inches in overall height. That's not 3.5% too large.

 

and a 305/20/22 is a lot bigger than a 285/25.....Dude I seriously did my tire homework and did the math before purchasing anything....This time in my life I can honestly say I know what I am speaking about, LOL.

 

Your Front to rear diameter variance is good, the diameter compared to your OEM tires (which should be 225/50/18) is quite high (.93" higher or 3.3%). This probably won't cause issues other than a bit of speedometer error but is typically best to keep under 3%. You probably won't notice any issues though. Guys on the Z boards change diameters for tracking now and then w/ % over that.
At any rate, you found a combo that's different and you're liking the setup so enjoy
But I'm still guessing the ride's a bit firm

 

Ride is probably firm for most but considering what I've been driving for the last 5 years I'm pretty use to it....I would post pictures of those rides but I'd probably get talked about some more, LOL...Every car I get I put 22's on, IDK why, just love that size wheel.

 

Like I said earlier, you're doing something different, and you love that wheel setup. Kudos for doing your homework on the tire variance, many don't with bad consequences. Enjoy your unique setup

Great idea.

 

Are those mud guards on your car?

 

Yeah for when I go off-roading.

 

I think they look good with the OEM ice-breaker, don't you?

Both are optional, qmantran. Although 99% of G's sold have splash guards.
