First off, i've done my searching and i found out some stuff but not everything. I already understand about the number on the tires, but my question come in which is best.
I've upgraded my tires to 17X8
a while back from the stock fittiing, and now its time to get some new rubber. Right now, I have 215/45/17
all around and im thinking unless if get other feedback thats what i might have to go back to.
But i'd like to change the size. I was think either 245/40/17
, or back to my original 215/45/17
. I understand the speedo problems, but i feel these tires all fall in a good range. Questions:
what r yall sitting on? Is it better to even mix them up, but some bigger on the back and smaller on the front. Also longevity is very important to me. Im 18 and on a budget
ghead , and im trying to squeze as long a life as i can out of em. So longevity and comfortability over performance.... (i dont race, its kind of pointless in my 318, but i do drive spirited.)
Also, is there a big difference in comfort when you switch from 45 to 40% profile? And would getting a larger foot, say 245 as opposed to 215 allow my wheels to last longer?
Any response, somehow related to the question of course
, would be much appreciated.
oh! and as a side note, how much does it cost to professionally mount tiresn on the rim and get them balanced. Im thinking about getting tires online cause their cheaper, but if the cost to mount and balance them overides my savings (cause at the shop they do that for free) then im just gonna get tires from the shop. I hope it doesnt' work this way, because i can find great deals online.....
