HELP! 235/35/19 and 19x7.5 +40 ?

[rxh5015]

SO i am getting new rims, and really like these 19's i found, but wont know if they would fit. (with a fender roll of course)

the rims.... 19x7.5 +40
tires.... 235/35/19

will the tire size be a good option?

also...what is a good tread wear for tires?
is 300 and above a good one?

Almost certainly, you will need a fender roll; even that may not be sufficient to avoid rubbing. The outer diameter of a 235/35R19 is very close to the outer diameter of the OEM 215/50R17, so you will not have significant speedometer or odometer error, and your gearing will be intact. With a 40 mm offset and the wider tires, the front end steering geometry will be affected somewhat (the projected axis from the steering input will not pass through the center of the contact patch at the pavement), but the deviation will be tolerable. A 35-series tire will be more harsh riding than the OEM size, and will have less of a gyroscopic effect (that is, the wheel will be more easily deflected by irregularities in the pavement, so more micro-steering adjustments will need to be made from the steering wheel).

As to what is a "good" treadwear rating, the answer depends on you. If you want your tires to last forever, and don't care about braking or cornering, the higher the better. There is pretty much an inverse correlation between how hard the tread compound is and how well the tire grips the road, and nearly as strong a direct correlation between how hard a tread compound is and how long the tire will wear. As a -rough- rule of thumb, then, a tire with a lower treadwear rating will be grippier, and a tire designed for performance will have a lower treadwear. The choice -- and the trade-off -- has to be your decision.

You can get Kumho SPT's for about $166 as a good, cost effective, summer tire in that size. Personally I went with the Bridgestone RE960as Pole Position
tires in that same size for $206 each. They are an all season, but a damn good performance tire as well, I drive to and from Charlotte, NC alot and some times a weather event will pop up unexpectedly during the winter and it may effect Raleigh, or just Charlotte, or neither and just hit Greensboro at my half way point in the trip at a more northern point that is more susceptible to winter weather...so I need that flexibility. But don't get me wrong, if it's too bad I'll call off work and hang with my girlfriend and say #@*& that!!

I have not had mine installed yet but the rims are 19x8 offset 42, obviously my fenders are fully rolled but I have yet to get the tires mounted on the rims as I am going to be putting the RPM "Street" lowering springs on next week and then I'll get the tires mounted up to install them, but I'll probably get the alignment before I put them on.

As far as the rims fitting goes, the 7.5 width will help you a little but it all depends on how that rim is designed really. I have seen guys with a drop and 45 offset rubbing with a slight roll and then others with a drop and a 40 offset rolled and not rubbing.
I'd recommend looking through the wheel guide in this section to get an idea on what other guys are running and if they are rolled and if they rub before and after...and someone may have the wheels you are looking at already installed.
Their is also a posting of guys with just 19's posted on it, if you do a search for 19's you should be able to locate it.


Alot goes into this and it takes time to get it all together properly.

first off i work at a tire shop so i see what will work and what wont as far as the 19x7.5 with a +40 offset you would need to do alot more than to do a fender roll to make them fit as far as the allinment you will have to do some work there to i cant remember the exact toe settings but you will have to toe the tires in just alittle to make it ware the tires alittle more evenly i would put it at .1 toed in from what stock is and when you get it alligned make sure to take it to a good shop that knows what they are doing and has a good allignment matchen

wow! thanks a lot guys.. A LOT OF GOOD INFO...i have heard that the 19's are more vulnerable to be dented by the roads...and roads in PA are horrible..as far as off set. i checked out the other forums and there are guys running 8.5 with a +42. so i would think there would be no problem fitting them woth sum adjustments. i took all of your advises.also... the cars is used more on high ways to go back and forth from college. sometimes it gets packed with a lot if stuff. that concerns me with 19's and the drop and the bad roads in PA..so taking in consideration your advise. i would probably be better off with 18's right? my driving is not agressive at all. so performance-wise on tires is not really what i would put a lot of though into. more into noise reduction and tread ware.so would 225/40/18 would be the right tire size for the 18x7.5 ? becaus i am seeing members with 215?

I have 235's on my car and I had to roll my fenders. It was a pain driving around with them unrolled.
My tires are almost the exact diameter of stock tires, so my speedometer is almost perfect.

The "choosing the right tire size" sticky says that 235/35R19 tires require at least 8" wide wheels.

19 X 7 ET40 = tsw kyalami right ?

they are actually R-1 racing gtr5 wheels ET40. they are 7.5x10 but i think i am going to go with 18's. Not truely decided yet. but more in to the 18's. what do you think? do you have 19's now? if you do. how are they for you?

this might be the most "newbie" question ever. but what exactly is a fender roll?
i have 235 tires wit my 18 inch rims and they rub a lot!
which is why i havent installed my subs in the back
because any little extra weight in the back messes me up
