Im getting some 17's for my lancer and they have rim and tire packages. The first package is all 4 rims w/ 205/40 tires and the second is all 4 rims w/215/45 tires. I know the 215's are wider and would give better tranction, but i dont really need it that bad considering they'll be off in the winter and im not doing any hardcore racing. The sidewall height is whats getting me. Is there a big difference in 40 and 45? Theres a 50$ increase for the 215/45 package. Whats your thoughts on this peeps?

 

theres a good difrence beetween the 40 and the 45 i have 40 my girlfreind has 45 i have to watch out for potholes she dosent

 

see if you can get 205/45

 

205/40/17 would be less total diameter and would make your speedometer fast and add miles to your car quicker. If you cant get 205/45 then definitly go for 215/45

 

I believe that 205/40 make your speed 3% off.... so if your speedo reads 100mph, you are really going 103. Not a huge difference

 

Anybody have pics of their car with 45 sidewall?

 

i got 205/40/17 and i feel ****ing rubbing on hard cornerings. but my car is dropped with progress springs, check profile.

i heard that some ppl with stock height experienced rubbage when installed 215/45/17.

but u also gotta put into account that ur car will be ALOT heavier. even with the rims i got the car is so much heavier, i can notice a visible decrease in acceleration by about 10-15%. on top of that, if ur someone who's gonna put big *** subs in the car, ur really asking for it.

 

Its not just the weight, its the weight and size of the wheels themselves. More mass= more for the motor to turn.

 

Ok, ok, ok, no no no. Heres the deal folks. 205-45-17 is the correct plus size for the Lancer, period. If you can only choose between 205-40 and 215-45, go with the 205-40. Heres why. I have 205-45-17s on my car, with Eibachs, and I have no rubbing issues. A 40 series tire will have a smaller diameter than the 45, so there should be NO rubbing issues with a 205-40-17. If your rubbing with a 40 series, you might have other issues. 215-45-17 is bad for two reasons. One is its 215 in width. In my and Tire Racks experience, 215 is too wide for the regular Lancer. You will for sure have rubbing issues. Also the 45 series is too tall, remember its an aspect ratio. 45 series on a 215 tire has a greater diameter than a 45 series on a 205 tire.

Also, adding bigger rims and tires to a car doesnt make it alot heavier. The car feels alot heavier because wheels and tires are unsprung weight. More force is need to start and stop the vehicle. So even though new rims might only add 40-100 lbs, it feels like alot more because it is unsprung weight. This is why forged rims are such a great idea. They can be made very light even in large fitments.

 

The ES stock tire diameter is different than the OZ, and 205/40 brings it as close to the same rolling diameter as you can get on the ES.

 

OK so if I go with the 205/40 am i gonna have any issues when i throw on my road race lowering springs? i thinkt hey said it drops it 1.3" in the front and 1.2" in the back? I could be a little off on that.

 

I have 205/40 with progress springs. The only time I rub is when I crank the wheel almost completely around while backing out of my driveway, and a tiny bit when doing a U-turn. Hard cornering hasn't been a problem.

 

I've had my car down as low as 2.75"+ with 205/40 and they won't rub under normal driving. Of course, hitting a speed bump, pothole, cutting the wheel, backing out of a driveway, etc. can cause it if you're going too fast. Just be careful.

 

Click on my name and see how the 215/40/17 tires look. I havent had any problems, i love them.

 

if your lowering your car then 205/45 will be the best size if you cant get it then get 205/40 or 215/40 they will both work with the right offset rims
