I think he means Discount Tire - their site also says America's Tire, so take your pick I guess.
 
Hey Tenberge, how about setting up your CarSpace page and posting some pics of your wheels?

You can get OEM 20's on ebay with tires...usually runs between $1500 - $2000. You can usually get the rims alone for around $1000.

2007 20" wheels on a 2003 Tahoe? by jmalik

Hi there. I own a 2003 Tahoe LT. I LOVE the 20" chrome wheels available on the 2007 Chevrolet Tahoe, and i inquired with a local chevy dealer (the parts dept) and he said that in order to fit 20" wheels on my 2003, I would need a suspension/lift kit upgrade, total you're looking at $7K (he wasn't trying to sell me on it, he was basically saying it wasn't worth it). He said that the maximum wheel size a 2003 can take is 17". Anyone know anything different about this?

Be aware that with significantly bigger wheels on any vehicle, you need to look at upgrading your brakes since the larger diameter wheel has more leverage and therefore harder to stop.

are you upgradint the rubber AND rim size, or just the rims?
if both then you need to have the speedometer recalibrated

Thanks Curious Gears. Tires and rims. Would a recalibration be required for 18" upgrade? A 17" upgrade? Many thanks..,.

Anything that changes the rolling diameter on the tire/wheel combo will require a recalibration both to correct your speedo and ABS. Your tire/wheel dealer can advise you if a particular package that you are considering would have a different rolling diameter than what you currently have.

Having upgraded wheels on all my SUV's over the years, the simplest thing to do is match the diamater of your existing factory wheels. Simpy go to a website that has tire diameter calculator, and use the calcular to size up different tire specs. (to go .25-.5" bigger diameter is no sin, since you actually go a tiny bit farther than the odometer shows).
 
The alternative of reprogramming the tire diameter into the vehicles computer requires a programmer, like Hypertech. Not a cheap solution, so its easier to match sizes.
 
Regarding the maximum wheel sizes, the dealer saying that 17' are the max is wrong. I had 20's on my '01 and '05 Yukons. Any aftermarket wheel with 15 to 25mm positive off-set works fine. Width would be 8.5 to 10". The rubber would be best at 285x55x20 (for 8.5-9" wheels) to 305x50x20 for 9.5-10" wheels).
 
Hint: The larger off-set of 20+ would be recommended for the 305 tires, to avoid an hard turn rub.
 
The 285x55x20 is the factory tire size (optional 20's) for the pre-07 Denali's and Escalades.
 
The problem with the '07 factory wheels (20's and 22's) is that the off-set is 31mm, which is a little TOO much for '01-06' SUV's.
 
Finally, the weight is a concern. The '01-06' brakes are certainaly better than the previous generation, but excessive weight has 2 effects.
 
1. The braking distance is increased due to weight.
 
2. The ride gets harsher and bouncier because of the extra weight being pushed on the springs and shocks.
 
If you have the bucks, look for forged wheels, rather than cast. They are very light-weight, stronger than cast, but expensive.
 
I bought 20" EVO Weld Wheels back in 2001, and the tire/wheel combo was lighter than stock. I got these after previously purchasing a cheaper set, that nearing knocked my teeth out, and made the steering a bit squirrely (seeking ruts in the road). Perhaps look for wheels that have less mass, like spoke styels. Check out the EVO AXIS-6 wheels. They are being discontinued, but the spoke style is illustrated well.

I beg to differ with your "expert". I have 18" on my 03 Tahoe with no lift. They look and ride excellent.

I ran 24" rims on my 2001 tahoe with no problems I ran 285/40/24 Pirelli tires with no rub.....Your dealer is full of it. I would not deal with them , as their ignorance will hurt you in the long run.
