Do aftermarket rims not fit Daytonas? (too much backspacing)

[daytonaturbo87]

Okay, today my brother went out and bought a set of 17" rims for his 92 daytona es. They're a 7" wide rim with a 40mm offset. Now we went and put one on his car and was amazed at there being only 7/8" clearance between the rim lip and the strut. Granted, if it would have a tire and weight on it, instead of being perched on a jack, there would be a little more clearance. But even with the Pumpers(with new winter tires on them if you're wondering) on the other side, I noted there's not a ton of clearance between the rim lip and the strut. Enough, but probably can't go too much less than that. Wanted to run some 225/45/17 tires on those rims, but that's not going to happen with this situation, so he returned the rims.

So I looked online and it seems pretty much all aftermarket rims in the 5 x 100mm bolt pattern are the 7" wide variety and have that same 40mm offset. A 7" rim with a 40mm offset has a full 1" of extra backspacing than a OEM pumper rim! Now Just by measuring, I can see even if we went with a 205 wide tire, it would still be way too tight, tire would probably roll onto the strut in a turn.

Surely there are people with Daytonas who run aftermarket rims. I could swear I've seen a few. How are you getting them to fit?!

[Clay]

well, stock pumpers are 6"wide, so there goes your extra inch of back spacing.

I think 205s will work, but most people running really wide tires either space them out a bit, OR run coil overs.

[Turbo3Iroc]

7/8" from the rim lip to the strut is more than enough. 225's should fit with out an issue. The tire isn't going to flex that much at the top, especially on a 45 series.

[JDAWG]

lol, on my truck I couldnt fit my finger between the wheel and the caliper but it doesnt move in and out so if it doesnt hit then you are ok

[daytonaturbo87]

Isn't that just too tight between the rim lip and the strut? I mean a 225/40/17 is going to be a wide tire and probably bulge off the rim a little, right? That 7/8" sure is not much clearance...? I really don't like the idea of using shims to make up that extra distance.

Caliper clearance is not a problem, no worries there. I've had vehicles a lot tighter there than this, but there's no motion there once the rim is bolted on.

I have 225/45-17s on my LeBaron (practically a G body) and they have PLENTY on room. They are on 17" x 7" factory wheels. I don't know the offset but trust me, there is more than enough room. The only issue you should have is that the tire could bump the frame rail on a complete turn which is why the Shelby Z had different bump stops in the rack.

The taller rim puts the tire closer to the strut and perch, you could find some tires with a 35mm offset, or buy some spacers.

What are those wheels off of?

[fleckster]

They are from a Stratus R/T sedan. Think they totally changed the look of my car. I used to have gray 16" x 6" LeBaron GTC lace wheels.

They look good on that car John! I would bet the offset on those is close to 40 as well.

They do look good but I would bet closer to 35 or even 30. Look how far they stick out, there almost flush with the fender lip. To get that on the van or if I want that on the R/T, I would have to use an 3/4 to an inch spacer.

[Turbo3Iroc]

I think the centers might stick out a bit giving that illusion of a lower offset.

Why would you need to space them out further?

[fleckster]

When Reeves comes up in a couple weeks to part out the GLHs with his Turbo Mini, we'll swap one of my wheels on it and see where it sets. I would almost guarantee that it will look the same in the wheelwell as my LeBaron.

No, no, lol, not John. I run stock TM wheels and they stick in too far, IMHO. I am running a 3/4 inch spacer on the van and it puts the wheels almost flush with the fender lip. Another bonus, the wheels no longer rub on full lock and I can run 24.5 slicks and not have them rub too, :clap:

[Turbo3Iroc]

I got ya Simon but with the additional width of the wheel it should be pretty close. Maybe the vans have slightly different clearances. I run a 8 mm spacer on my 24.5's on Kosei's but no spacer on my 17x8s with 245/40s which come out to be a bit taller than the slicks.

Thats true, I forgot that they are 7 inch wheels, mine are 6 inch. :nod:

[CSXT802]

I running a 17x7 rim with 38mm offset with 225 45 17 tires. no issues other than the normal rub on a full lock turn.

[Vigo]

17x7 with 40mm will fit easily with 225s.. 7/8s is PLENTY. i think on my dynasty i have less than 1/4.. it doesnt really deflect at the top, only the bottom, so its all good.

[Reaper1]

On my Shelby Z I run 16x7" wheels with 35mm backspacing. With my 225/50/16 tires and my -1* camber I can't fit my pinky in between the tire and strut housing! There is plenty enough room between the tire and the bottom of the spring perch though.

I've had the wheels off a few times and there's NO evidence of any rubbing on the struts at all!

The wheels are Enkie RPF1's...

[daytonaturbo87]

Thanks for the info reaper! Good to know the tire doesn't move around up there at all. Well we went ahead and ordered two tires in the 205/50/17 size and two in the 225/45/17 size. Same overall diameter. We'll put the wide ones in the back, but test-fit them in the front so next time we'll know for sure that we can indeed do the 225's. The 205's fit fairly tight up front, about 1.5 widths of the tip of my finger(and I have small fingers). I think the 225's would have been real close, but we'll find out. If he ever takes the car to the track it's no big deal to swap front to rear for the day. But right now the whopping 140hp of the 3.0 isn't exactly demanding on tires! LOL.

[Reaper1]

You do realize that the 205/50/17 tire is taller than the 225/45/17 which taller yet than my 225/50/16, right? It's not *much* different, but they ARE different! You might want to check on Tire Rack to make sure that manufacturer of tire may take that in to account as they are good about giving that kind of information about tires on that site. Better safe than sorry! I know *MY* Kumho MX's are slightly taller than what the tire size calculator came up with, but not by much.

BTW, I'm using this tire size calculator:
http://miata.net/garage/tirecalc.html

[Turbo3Iroc]

They are only 0.10" off which I see as nothing.

This is the calc I use: http://www.dakota-truck.net/CGI-BIN/TireCalc.cgi

[Ondonti]

7/8" is a huge amount of space. I run much much less then that. Less then 1/2" on my Spirit. And thats with 225/65r15 tires. Tons of sidewall and only a 6" rim so lots of bulge.

And coilovers are ZERO help when it comes to strut problems. The Perch really is not an issue for people, its the side clearance.

[Vigo]

yeh because most people run shorter than stock tires, not taller.. 225/65r15 are way on the tall side of what most people use. ive run between 23" and 25.5" tires on my cars, never hit the perch. that really only comes up on L-bodies i think.

[glht_omni]

225/45/17 is the exact same overall height and width as the stock 205/60/15 and i am running 225/60/15 on my r/t with some rub on the bumper but none on the caliper or strut and they are .94" taller and .86" wider.

i think you would be alright with the 225/45/17 if you still had 7/8" clearance with the wheel mounted like kelly said.

[jrye68]

i run 245/45/zr17 with no problems other then a slight rub on the front bumper cover but not enough to do any damage.

[Turbo3Iroc]

What body car and what size and offset wheel?

[Speedeuphoria]

i run 245/45/zr17 with no problems other then a slight rub on the front bumper cover but not enough to do any damage.

lets see some pics!

[glht_omni]

ditto, that aint fitting on a spirit, i guarantee it.

[Speedeuphoria]

Its not fitting on stock struts either, he's got a daytona but I think its similar. I know they deff dont fit a spirit with "slight rub". Its deff not a bolt on affair on any TD model

[Reaper1]

They *MIGHT* fit on a G-body with a slight amount of rubbing depending on the manufacturer, but I'd be inclined to think that they would be a bit too tall to fit without rubbing.

My 225/50/16's BARELY fit without rubbing, so....*shrugs*....

[daytonaturbo87]

Well we bought two tires of the 205/50/15 variety and ordered two in the 225/45/17 size. Bolted on the two 205's and they fit. Very close but they fit. We'll see how the 225's do when they come in. Height difference is going to be so little between the two I'm not worried about that at all.

You mean 205/50/17 right?

[Vigo]

my 245/40r17s are definitely 'bolt on' on stock struts but /45 series are noticeably taller and would rub more.

[daytonaturbo87]

Yes...........

[turbodaytona87]

My car would be running too if I had my turbo:mad:
