Ok guys i get a decent amount of emails asking me basic fitment questions on what wheel sizes will fit our Altimas.

First, the bolt pattern is 5x114.3 (some places may call it 5x114, dont get nervous)

Lug Nut size is 12 x 1.25 (make sure to pick up a thin wall socket)

Something that is very important is staying close to the stock diameter of the entire tire/wheel combination.

It's all about the offset!
Offset is the distance of the mounting plate to the center of the wheel. See diagram below:
Image
The smaller the offset, the more the wheel will sit flush to the fender (or stick out) if that's the look you're looking for. For instance; a 8.5 width rim with an offset of +30 will be flush to the outside of the fender.

Check this site out. http://www.miata.net/garage/tirecalc.html Once you find the wheel you like, use that to find the right tire size.

3.5 Stock Information 17x7.5 26.3" Diameter +45 offset ---> 215 / 55/ 17. This means, the tire is 215mm wide, the side wall is 55% of the width of the tire (215 x .55 = 11.825cm) ... 11.825cm / 2.54cm per inch = 4.655 inches for each side wall. 4.655 x 2 (two sidewalls)= 9.31 inches + 17 inches (size of wheel) is 26.31 inches. (incase you wanted the math)

So for a 20" rim, you could get a 225, 235, 245, or 255 cm wide tire, however, note that when you go wider with the tire, the smaller the sidewall is gonna be in order to fit close to factory specs. And the smaller the sidewall, the more uncomfortable the ride will be.

For 20" rims, here are some possible tires to stay close to factory specs

225/30/20 = 25.31225/35/20 = 26.2225/40/20 = 27.08

235/30/20 = 25.55235/35/20 = 26.47235/40/20 = 27.4

245/30/20 = 25.78245/35/20 = 26.75245/40/20 = 27.71

The ones in bold are the closest to factory specs. You can do the same equation above for 18 and 19" rims

Some specs on 19s19x8:225/40/19 = 26.1"235/40/19 = 26.4"

19x8.5:235/40/19 = 26.4"

And some on 18s18x8 on 235/45/18 will get you to EXACT factory specs (26.3") but 225/45/18 (26.0") is damn close enough and tires are a lot cheaper.

This info is for the 08 Altima Coupe and is a work in progress... Chime in with your fitment/offset/drop

ALL Stock Infiniti G wheels will fit.

Ovrbst had NO RUBS with a staggered 19x9x5 fronts and 19x10.5 rear setup (no drop, that would cause issues)

I will be "sweeping up" the thread to make it very easy to understand.

here's the calculator I use:http://www.powerdog.com/tiresize.cgi

here's how it worksyou copy paste this (if you are a 3.5SE):215/55/17 as the first line, you hit "ENTER" on your keyboard to go to the line below, and then you type the tire size you want to check .

eg: 245/40/19

it will tell you all you need to know

a good guideline is to try to stay plus (+) or minus (-) 3% from factory specs

Peoples have been able to run anything up to 9.5 inch wide rims with an offset from +45 to +25 without rubbing on the 3.5SE's firm suspension.for the tire size, just check the calculator to see that your "Diameter" isn't more than one inch taller than stock (again if you have 3.5SEs) and it will not rub.

Hope that helps

For those looking at 19"s--

The stock radius of the 3.5 is 215/55/17s which equals a radius of 334.01 mm. (like LBC mentioned in inches)

New Tire Size / Radius in mm / mm difference in height off the ground from stock235/35R19 / 323.34 mm / -10.67 mm difference / -3.2%235/40R19 / 335.28 mm / +1.27 mm difference / +0.3%245/35R19 / 326.89 mm / -7.12 mm difference / -2.1%245/40R19 / 339.09 mm / +5.08 mm difference / +1.5%

Like mcheddadi mentioned, you dont want anything + or - 3% over factory specs. This is due not only to fitment issues, but also the effectiveness of your factory brakes.

My question to the experts here is the following:I am getting 19x8 5x114.3 wheels. I have the Eibach drop.If I buy 245/40/19, I will gain +5.08 mm of height off the pavement correct?Is this a good size that you all would recommend? Seems the most logical as it raises my car a few mm, is 1.5% close to stock size and fills my wheel wells a bit more.

The stock 3.5 tires have a +45 offset. That should not affect my new tires correct? My new ones are the Konig ET30, so that is the +30 offset? Would the change in offset affect my handling or would I need anything special for the wheels?

you won't rub, don't worry. LBC has less firm suspentions and 20s with a worst offset and he doesn't rub after the drop.

I have 245/40/19 on +40 with hubcentric spacers and I don't rub with the drop

this calculator does the computation to one more decimal point and also will show how far off your speed readings will be at different speeds.I like how mcheddadis one shows how far off your odometer will be.

So a 3.5 Coupe with new 19x8 5x114.3 wheels (offset of 30), 245/40/19 tires, and the Eibach drop won't have any issues? Good deal.

My last question before I buy my tires is will I need any spacers or new bolts to attach my new wheels or can I use the bolts that came with my 3.5 coupe? (I also bought a set of the special bolts (4 total, 1 per wheel) so noone steals my wheels).

No reason to get one unless he wants push out wheel even farther from the hub. Which in this case is not a good idea as hes already aggressive.

You don't need it. They are spacers with a built in hub support. The more important one is getting hubcentric rings if the inner hub bore of your wheel doesn't match to OEM spec, which is 66.1 mm. In your case, the Konig wheels hub bore size is 73mm, which means you will need hubcentric rings. Whoever you bought the wheels from should of supplied you with them.

Your pushing the limit, but your wheels will be flushed.

No you don't need any new spacers. I am assuming your talking about lugnuts when your saying bolts. The stock 3.5 lugnuts should work with your new wheels.

Yep that'd be it. Forgive my "noobness".

Cheers for the info Loop!

Does a purchase of new wheels usually include the hubcentric rings? If not, where do you recommend to pick them up from and how much should I be looking to spend boss?

Most of what you guys are talking about is on the 3.5, but i imagine its the same for the 2.5? Correct me if i'm wrong please. Also would 245/35/19s have any problem on a 2.5?

with 10inch width you'd be pushing new boundaries lol.

I don't know for sure, it depends on the tire size and the width of the inner fender well. I know some did 9.5 without a drop. but i'm not so sure about 10 with a drop

Premium 3.5SE AC Wheels will fit on a 2.5 right? I figure since the cars are the same dimensions mostly and the bolt patterns are the same...

Nope, just clarifying. I'm still new to this tire stuff. Too many things to consider when purchasing new wheels-- especially tires anyway...

Thanks for all the help folks!

I meant hubcap sizes. My Altima is the base price 08 coupe. It came with hubcaps with those ugly plastic wanna be rim placements over them lol I think ima get those I posted earlier, just waiting for finance to get back to me.Thanks for explaining the size thing to me tho, I had no clue what any of it meant. New to cars I guess you could say.

OK, ill make it REAL SIMPLE. YOU CAN FIT ANYTHING UP TO 24 INCHES.

k?

the only factor you need to worry about is OFFSET, RIM WIDTH and TIRE SIZE
