unless the circumference of the larger wheel/tire is increased, the side wall of the lower profile tire will be lower than that of the higher profile tire (with constant diameter, the side wall of a tire on a 20" wheel is 1 inch lower than a tire on a 18" wheel, the width of the wheel/tire notwithstanding). With lower sidewall comes stiffer ride and more susceptibility to wheel damage.

 

mm... yes.. i love the BBS look i am an audi/VW owner too.. and i gotta say the 1st one is still my favorite... those BBS are

 

nice photoshop my favorite is the second pic also can you fit 20's on the new IS ??

 

Sweet!!! Good job on the photochop!

What a coincidence, I say a beemer 5 series last night....and I was thinking if I changed the wheels on the IS, it would have to be with a set of HRE.

Now I know for sure.....I just did not know about fit, whether they made them with our bolt pattern, as they are typically made for European vehicles.

 

Those photoshops are awesome!!!

My absolute favorite choice is the first HRE wheels - I wish I could afford those in 20's for my GS.........

That's my point exactly, with a staggered tire package which yields the 30series rear tire the section width is wider thus the sidewall is very close to that of the front tire which is more narrow. Its not like you run a 235/35 front and 235/30 rear. We get a lot of clients that ask thing like, "why can't I run a 245/35 and 275/35 because I don't want to have that 30 series rear" then they see the tires and say "oh, thats what he meant".

 

Thanks for the comments everyone... and looks like a couple salesmen popped out of the woodwork. Good to see.

I think 18's/19's may be the best call - By the way, I forgot to mention that since I got my 250 in frozen Calgary AB, I asked them to throw on Alpine Pilot winter tires in the deal, so I only have 16's = I need a set of summers with 18/19's. (see first pic, this is my actual car - don't make fun of my 16's, I love this car and yes, I realize it looks average with 16's)

I was chatting with a few friends last night during new years and they all agree, while 20's would look pimp, they're not exactly practical for a daily driver.

So for all you who asked for more PS, here it is... dial-up beware ( I threw some NEEPER love in there for the BLING lovers)

 

one more for mr. BBS ...

 

I think we are talking about 2 different things: the concern was that if the tire circumference was kept close to stock, by going to a larger diameter wheel, you would need to decrease the tire's side wall height (even if you go with wider tires). With the edge of the wheel closer to the ground, there is more risk for damage.

 

Love those 840 HRE

 

Those 540s are saweet!
