my tires need to be changed , am thinking of going bigger or wider but i dont know what to choose

i have a 2005 sedan , and am thinking of a 2 inch drop, will either of those tires affect preformance ?? or ride comfort ??

thanks a lot and sorry for the long post

those two tires are pretty much the same as each other...but a lot of dynamic variables go into each tire...

the pros of 215/40/17:
-lower profile = less-er tire wall flex = better handling/cornering
-215/40 tire will be lighter than the 215/45. usually about 3-5lbs lighter. this means your car will respond slightly better (and i can confirm this). remember, every pound of dynamic weight is equivalent to 3 pounds of static weight.

the cons of 215/40/17
it is slightly smaller than OEM speedo ration. 1.8% faster to be exact. this means when your speedo says 60mph, you are actually going 58.9 mph.


the pros of 215/45/17
-you get a little bit more tirewall, so it'll help with the ride comfort. but remember, this factor is negligible. you wont feel a difference in real life.
-you will get a bigger contact patch compared to the 215/40. this is due to the extra sidewall that allows for more of the "215" to touch the ground.
-this size is slightly larger than oem size. 1.7% too big to be exact. so when your speedo says ur going 60mph, you are actually going 61
-you will also find more tires in this size than the other. this is a more common size.

cons of 215/45/17
-its a bit heaver, which will make your car a little more sluggish. most people wont feel it, especially if u have an automatic. i have a manual in my car and i am very sensitive to every bit of change in my car.

and remember tire construction differs from manufacture to manufacture (as far as actual size goes.

a falken azenis 615k 215/45/17 (semi slick street/race competition tire) is different than a dunlop all season 215/45/17 tire....

i am currently running falken azenis 615k in 215/45/17.

the tire profile is pretty thin (aka thin side wall). if you live in an area that has lots of uneven pavement, i can see a problem with it.

if i had to recommend you a tire size (this is prob the only real answer you were looking for), i would recomend the 215/45/17.

why? because there are a lot more pro's of the 215/45 over the 215/40.

bigger contact patch, better shock absorption, and a good amount of sidewall aka "meat" on the tire. the 215/40 in my opinion is a little on the small side.

Very informative^^· One error tho, he wanted the comparison between a 215/45 vs 225/40

225 - potentially will rub or fenders or suspension components, depending on wheel off-set. again, potentially, same 225 could have different dimensions depending on tire model/size/manufacturer, but still whithin TRA standards.

to my defense, i was prob drunk as funk. lol

i wouldnt do 225/40 will be real heavy and you are better off spending money on a 215 tire that is nice and sticky.

1. lighter tire than the 225
2. stickery


remember that just beacuse its a 225 doesnt mean it has a bigger contact patch.

a race/sticky orientated (like the falken azenis 615k) has more "contact patch" in the 215 width than a "all season" 225. just something else to consider. just something to consider.


is there any reason why you'd want to go 225/40/17? that tire size is kind hard to find as well...you will have a very very limited selection with that specific size (another thing to consider)

pb_boosted_es2

Lol, no prob with that.
But yea i jus switched up my wheels last week. Got some 17x7.5
Car feels a bit better. Wasn't bad before, just had a bit of gap with my 16x8 due to the fact i couldn't lower my car anymore due to rubbing probs of my 3" exhaust. Now i just gotta roll my fenders some more. Possibly even pull them a bit.

And i think it's time to update my signature. Haven't been on in over a yr.

thanks guys ! i am getting the 215/45 ZR17s next week i had a lot of wheel spinning with the old (215/45s) thats why am going bigger .

should i roll my fenders ? esp that my car is dropped around 2 inches ??
and should i be afraid of fender rubbing with the 215/45s ?

and again sl33pyriceboi thanks your posts have ben VERY informative !!

you might rub with the 215 but it depends on your wheels and the offset.

i have mine rolled and i barely clear the rear and i am dropped close to 4"

it never hurts to roll your fenders and i would suggest it.

as for me, i DID rub with 215/50/16 tires. then i rolled it. then i didnt have a problem. then when i put on my 215/40/17, i didnt have a problem either.

215/45R17 Yokohama AS530....great tire in this size. 500 treadwear AA traction and A temperature. Semi-agreesive asymetrical tread pattern, great all weather, all season handling. I would stay away from the Falken's...they tend to seperate and wear terribly even with good alignment and keeping up on rotations and balancing. Good Luck!

^and your proof from comes?

ive burned thru falken 912, falken 512 and falken 615k....and ive managed to make them all slicks with even wear.

ive ridden on the Yokohama AS530 on a few TSX with similar tire size... and they weren't impressive to say the least....there are also plenty of reviews on acurazine that confirms they suck. nothing personal.
