im planning on buying some RPM2's they are very affordable compared to forgeline wheels.

now when i was choosing the size the computer says 17x9 with 40 offset will fit?

is this gona rub in the front?

i was thinking about 235 or 245 45's in the front and 255 or 265 45's in the rear?

i have stock suspension but may get tokico shocks someday.

the car is VR FD.

was going to order the wheels from discount tire since they having some sort of special if u apply for when of their store cards. can they order different offsets you think?

 

They should make a 17x8 +38 and 17x9 +45. This would be the setup for the FD. I can get you an amazing price on this setup. Please feel free to PM me with the best advertised price you've gotten and I'm sure we'll beat it for you. I can offer you tire and wheel package deal with specific tires we get great deals on. Falken, Toyo to name a couple.

how come you didn't sell me that offset. you sold me the +40 in the front and it rubbed a whole in the front fender liner with the 235's. all the way into the wiring harness. hey potato, i sold it to a guy with tokikos and they rub pretty bad. so if i were you i try to get a +38 off set. kvn

 

I read thru this too quickly. The 17x9 +40 might work with a 245/40/17. It all depends on the suspension and lowering you have. I was advising to go with a staggered setup. 8" Front and 9" Rear.

The +38 will be moving the wheel towards the fender so definitely don't go that way.

The offsets are such:

17x8 +45 or +35 and 17x9 +40 rear.

Rishie hooked me up with that setup. Fits really nice.

 

So if I'm reading this correctly, there's no way to get a 17x9 RPM2 into the front without rubbing? How about if the car has coilovers (Tein Flex, spring rate ~ 650 front, ~ 450 rear) and is lowered about 1.25" in the front and 1.5" in the rear?

I was thinking this size wheel would fit with a 255 or 265 width tire (and whatever profile, 35/40?) all the way around.

 

I run an 18x9 +42 up front w/ 255/35/18's... I do have rolled fenders, but i also run very low... with a 235 or 245 section tire you should be OK.... 'course if all your going to run is a 235, you might as well just get the 8" wheel.

 

You can totally run a 17x9 up front. You can run 10's if you want. It all comes down to the offset of the wheel. A +45 to +50 would be ideal in the front.

Ok, so the guy in the beginning just had too small a offset (because Enkei doesn't make any offset higher than a 17x9 with 40 offset) and given he was only talking about a 234/245 series tire anyway you suggested 17x8's for the front?

 

You might try 17x9" +40 all around w/255/40/17. or a 255/40, 265/40 combo, or a 245/40, 255/40 combo.

Stay away from the 45-series front tires.

 

I rubbed with 17x9 +43 with 255/40/17 in front (with aftermarket springs).

 

Oh you have to take into consideration the model of tire you are using as well. Varying sidewall designs and section widths can also have an effect.

40 is way too thin a tire for me, i had those before and HATED it. i feel bad for guys running 35s on the street. anyway, ill send a PM in the next few weeks when ive decided on the tires. thanx for helping

 

A caveat:

As i've often said ALL lowered FD's with aftermarket wheels rub. Its a fact of life, the front wheel wells are small.... unless you can afford custom modulars with 50 mmm offsets like the stack wheels... you'll get some fender liner rubbage with the wheel fully turned, or when you hit a bump. I've never seen a lowered FD, particularly w/ aftermarket wheels that doesn't have rubs in the liners.

The main thing is to keep them off the lips... I would recommewnd rolling them for safety, and using a shorter, wider, rather than taller, narrower tire.

I've run a lot of combos on my cars:

17x8 +38 all around w/ 245/40/17

17x8 +38 front w/ 235/45/17, and 17x9 +45 rear w/ 275/40/17

17x8.5 +37 front w/ 235/45/17 and 17x10 +44 rear w/ 275/40/17

18x8.5 +38 front w/235/40/18 and 18x9.5 +45 rear w/ 285/30/18

18x9 +42 front w/ 255/35/18 and 18x10 +42 rear w/ 275/35/18


All worked, all rubbed... with Koni/Eibach pro kits at two different perch heights, and Koni GC coilovers at 25" fender heights.

 

At what width? A 255/40 tire isn't that thin... its the stock rear tire on later model RX7's, and makes a great front tire.... you know it varies with width right? a 215/40/17 isn't the same as a 255/40/17

 

I agree. I was just making it known that the combo I quoted will most likely need the front fenders rolled with lowering springs installed.

I just didn't want to see a "You said try this and now I'm rubbing" post later down the line.

 

the common width ive used in the past is 225/40/17 and 225/45/17

there is a huge difference in feel. i can enjoy the 45 but not the 40s...

i most likely will never get lowering springs. the car already scrapes going into drive ways, and after a new front bumper, im sure ill be parking on the curb side quite often.

those tein springs on ebay are priced well, i might consider those in the future though when i get some tokicos.

so if i stick with

235/45/17 17x8 +45 front
255/45/17 17x9 +40 rear

this is what im looking for in a staggered setup?

 

FYI,
A 245/40/17 has nearly the same size sidewall as a 225/45/17, and a 255/40/17 DOES have the same size sidewall as a 225/45/17 (roughly 25" or so, give or take a little for brand).

The "40" or "45" number is a percentage of the width... so a 275/40/17 is much taller than a 225/40/17.

a 225/40/17 is the wrong tire for our cars... its only about 24" in diameter, a whole inch shorter than the stock tires, yet on a 1" larger rim. Better get a kidney belt.

255/45/17 is too tall... a whole inch taller than stock at 26"

 

the 225s were on 17x7s not on the stocks though, this is what ive had on other cars too, not just the RX7, so im basing the harshness from more than 1 vehicle. i believe the 225/40 tires were yokohama A520s. so those are pretty rough by them selves


so you recommend in run 255/40/17 in the back for a more even height in front and rear?

 

If you want to maintain an even ride height, running 265/40s in the rear would be best with 235/45 fronts. This setup will understeer a hair more.

This is a very common setup in 18s as well (235/40 and 265/35 in that case).

 

... just remember... the sidewall height varies even on "40-series" tires. ... those 225/40/17's had TINY sidewalls... about 3.5".

A 245/40 is over 3/5" taller overall, and a 255/40 a whole inch taller (resulting in 4" sidewalls).

I think it's worthwhile to keep the overall heights similar, front to rear, but it isn't worth being obsessive about. Logic would say that you'd want to avoid making the front taller than the rear, but yet Mazda used the 235/45/17, 255/40/17 combo on later models.... you could use any combo of a 265/40/17 or 255/40/17 rear, and either 245/40/17, 255/40/17 front and be fine.

 

will 265 fit on the 9" wide wheels without fitment issues? or will i need 17x10?

 

ok the final decision is

17x8 +35 235/45/17

17x9 +40 255/40/17

tires im going to order are the toyo t1-s. was gona get the MX but people have said the toyos are better and just for a few dollars more.

i called discout tire and they can special order the RPM2s for about 212$ each. tried to get in touch with ARD but seems i couldnt.

 

also the car is stock height so there should be no rubbing at all right?

 

now im all confused and talking to myself.

ok so lower offset moves towards the fender?

fd3virgin says his 17x8 40s are rubbing in the front?

so if i got 17x8 35s they would stick out farther and rub even more?

so i need

17x8 +45 front
17x9 +40 rear

that sound right?
