235/45/17's on a 17x7 G35 Sedan rim? Will they fit?

Grant or Luke? Anyone done this and given feedback. 235/45's are a whole lot cheaper than 235/50's.

I understand the speedometer/odometer/ride quality issues. I also will consider the loss of peak performance for these particular tires. It will still be better than stock size.

But for around 180.00 per tire I can have the Michelin Pilot Sports which are not available in my current size or in 235/50 (A/S but not summer)

Can it be done?

IMHO, this will be better cause I spend a lot of time on the sidewalls.

Please pass out advice.

keep the 235-50-17. I could ahve sworn the g35 4-door came with 215-55-17...but either way, a 235-50-17 and a nice set of bridgestones or the sport a/s will server you well, the 235-45-17 will do a few thinugs you dont want:-speedo/abs error-decreased load capacity

both very, very bad items. also, because of the lower sidewall height, it will be pinched on a 7" rim, not desirable at all for good handling ad performance.

with a Pzero, RE40 and A/S available, you've got enough high performance options to keep yourself entertained.

yes the 4 door comes stock with 215's but 215 is just not enough width to keep the tires from spinning when you have 230 whp or more. 235's will barely do that but I prize the stock look and the rims are a big part of that.

235/50's are what I had on my altima and will likely go with them again

No, it looks real good. I had 235/50/17's Pilot Sport A/S's on my 2k2 altima with 17x7 wheels (which is right in the middle of the recommended width). I still had traction problem on starts even with that width, which is why I want a true performance tire instead of a (even slightly) compromised tire

That is also why I would like to run 245/45's to get mo betta traction

...you wont get 'mo betta' anything. Please search around on this, contact patch does not get bigger by using a wider tire, so just get a nice sticky tire and be happy...

Chet, will i loose alot of sidewall stiffness if i used a 235 tire on a 7" wide wheel? would u reccomend a 225 over that... i know 225 is 'optimal' from wat some consider the width for a 7" rim, i have 205/40s on there and they are just too skinny (came with the wheels i bought from my buddy with an integra)

a 215-45-17 is near perfect on 240's with a 7" wide wheel, a 235 will bulge badly(just ask jerome and russ...) and its a full 1" less than reccomended wheel width in any 235-40 tire(if you have a 235-45-17, it wants a 7.5 minimum) the widest I would go on a 7" would be a 225, but a 225 is ideal(in 40,45, and 50 apect ratios) on a 7.5"

a 215-45-17 would work great...and the es-100's are cheap in that size :)-chetwhat aspect ratio were you considering for the tires? 45? 40?

no, a 225-45-17 wouldnt be bad, but its still pushing the envelope of a 7" wheel...

its better than a 235 :)

its been done, but I dont reccomend it, it does pinch the bead a bit, but its still in the "Acceptable" rim range..

you dont gain much, if anything from a handling perspective(other than getting stickier tires), since your total contact patch area stays the same.

I put those on(pilot sport A/S) a gentlemans G35 by his explicit request and called him back a few days later, he said they work great, but feel less "settled" than the A/s I put on his M3...-chet

Okay, I guess I'm a bit confused now. Earlier in the post you had said that the 235-50-17 setup was okay on the g35 instead of the stock 215-55-17. But then you mention that you don't recommend it. I may be misinterpreting it though.

I'm looking at the Pilot sport A/S's for my g35X on the stock rims as a replacements for the Goodyear RSA's that came with the car. Because of the limited tires available in the size, Iwas looking to go to the 235-50-17's instead. I'm basically looking for a decent all-season tire that will keep the good road manners of the car. nothing for racing or anything like that. I figured that the Pilots would fit the bill.

Do not make me explain this again... I will beat you to death with a stick.

A wider tire CAN have a wider contact patch.

"A wider tire CAN have a wider contact patch."

I didnt say it wasnt wider, goober. you sound like me with the "I'm not explaining this again" things. haha.

it will get wider, but the overall area stays the same unless you reduce air pressure, increase the weight on the tire, etc..;)

EXACTLY... so when the car squats on the rear tires it will increase the area.

Homeslice.... :D

yes 235/50 and 235/45 are not the best sizes for a 17x7 wheel. I agree with all of you there. For the 240sx stick to 215 or 225, unless you have power adders. In that case invest in wider wheels.

BUT

BUT

BUT,

for the g35 sedan, there are not many good TIRES out there to take advantage of the G's suspension and power. To get the best tire compound (i.e. S-O3's or Ecsta MX's or similar) you have to run some unconventional sizes. I know a guy running 235/45's S-03's on a 17x7 rim with good results and a coupla people who squeezed 245/45 azenis on a 17x7 rim. The azenis guys autocross the tire with excellent results. NO it is not the best solution but once you get that world class rubber on your rim, even if you are only using it to 70 or 80 % of its available contact patch, you will get much better than OEM results and better than any 225 size tire as well. Just recently Avon Tyre hit the american tire market with teh Tech M500 tire which IS available in 215/55/17 for the G sedan. I think that will be my next tire as well.

When you are driving a first year car (unlike a Q or a 240) there are not as many people who have tried everything yet to advise you so you have to make due. Me, I tried teh Goodyear GS-D3's in 225/55 and I like them
