View Full Version : will 18s be better than 19s???

05-18-2005, 05:26 PM
Do you guys think it would be bad if i got 19s on my 99 a4 quattro instead of 18s??? Will I notice a negative diffrence if i get 19s???

05-18-2005, 05:32 PM
well from what ive heard, 17" is really the best rim handling wise
with the 18 right behind it. I read this in car and driver a while ago. thing is the sidewall gets to stiff because of the lower profile and loses traction.

if i get 18s, will i rub with H&R Race Springs??

05-18-2005, 05:52 PM
NO..... i have H&R Sport springs with 18s and i dont rub even when i have people in the back. With 19s though i bet you would rub

05-18-2005, 06:20 PM
I rubbed with H&R Race springs and 18s. I had 225/50/18 tires and it rubbed up front when I turned, never in the back though.

05-18-2005, 06:27 PM
audi 1.8 can you post a pic of your car for me please?? I really want to see what sport springs look like with 18s. Also if i get race springs will there be anyway i will be able to deal with the rubbing issue???Is it loud?

05-18-2005, 06:33 PM
I think if you roll the fenders that you're not gonna have rubing issues. It was loud though, and the worst part was that the fendrs actually tore up my tires.

That's a huge sidewall dude...I have 40s, and they're slightly larger than stock wheels and tires...Not only would you rub, but your speedo would be way out of wack.

05-18-2005, 08:10 PM
wow. who gave you advice on getting 225/50s?

The size should have been 235/35 or 225/40s for 18" wheels to properly fit.

05-18-2005, 08:34 PM
can someone explain what these numbers (225/50/18)mean when it comes to tires?

05-18-2005, 08:42 PM
i hav h&r race springs with my 19x8, my tires are 235/35/19, the only time mine rubbed was wen i hit decent sized bumps with the wheel turned, so i jus rolled the lip in the fender well up and trimmed out som of the plastic liner and now no more rubbing

05-18-2005, 09:00 PM
225/50...What??...Thats nutz!!!!!!

05-18-2005, 09:02 PM
so whats the first number, second, and third stand for??

05-18-2005, 09:30 PM
anyone there?

05-18-2005, 09:55 PM
so it goes

width/sidewall/???(whats the last number?)

05-18-2005, 09:58 PM
Uh, diameter.

A4 in SC

235 is the nominal tread width.

40 is the aspect ratio. In other words, it's the percentage of the treadwidth, i.e. 40% of 235mm.

18 is the wheel diameter, so yes, these two HAVE to match in order to put 18" tires on 18" wheels. I've never heard of anyone trying to put different diameter tires on different size wheels, but I'm sure it's been tried SOMEWHERE!

Hope this makes sense.

Actually, for more info, why not post this on the wheel and tire forum? This is more general info on tires than B5 specific.

We all know how I feel about 19"

It is all dependent on tire manufacture and what you want... i.e. better handling, looks, and the enviroment you drive in and what you can afford.

I'm old school... I prefer one size up from stock and a better all around wet/dry tire.

I have not yet stepped up in size 16>17 cause the wife drives the car too and has messed up a few rims on me.
I am a Yokohama advocate. Why? I tired several tires on our A4 since new and have found the AVS ES100's to be good handling/wear for the dollar.

Bottom line:
It all depends what you want and how big your wallet is.

Eventually I will go one size up from stock and get lighter wheels to reduce unsprung weight.

I don't like the huge wheels and tires that have a small shoulder. Don't like replacing wheels due to damage and spending $$$ to replace an expensive tire.
If you are a single guy and tons of money to spend then go for the bigger stuff.
If you are cost aware person like me and want the best bang for the buck, then do some digging around.
Talk with the Tire Rack guys in here and they can help you as well.
Just my 2cents worth.

rule of thumb - the bigger the wheel, the heavier the wheel and the rougher the ride as it decreases sidewall.

17's are better performing than 18" but don't look as cool (in my opinion). If you are hell bent on going 18 or higher.. forget about throwing race springs and stiff adjustables on it - you are just going to wear out your car and rattle your teeth out all while losing performance and grip.... but some poeple think that is cool so it is all your perogotive [:D]

05-19-2005, 04:00 PM
well if you say i shouldnt put race springs on my a4 if i put 18s on it, then are you saying i should put 18s on it and just keep the stock suspension???(that would look terrible)

05-19-2005, 04:01 PM
use sport springs dude... race springs and bigger wheels wil just over stiff your ride.. use sport springs with a moderately valved shock (not the stock shocks).

05-19-2005, 05:33 PM
19s for show, 17s for perfromance, 18s for a mix

05-19-2005, 07:19 PM
i hate the gap that sport springs leave.

05-19-2005, 07:26 PM

DDQ how are your race springs going?

05-21-2005, 09:05 AM
I have a set of 19" RS4 with Neuspeed Sport springs and Bilstein sports shocks. At first only the front end was rubbing whenever I turn but now, no more rubbing unless I go over some serious bumps.

However, where I live, Montreal, Quebec, has terrible roads. Huge potholes after every winter. I have bent both of my front rims. I didn't have any issues when I was riding with my 18".
