305's are too freakin wide
 
Found out the hard way $$ yesterday that 305/30/19's a on a 19x10.5 wheels with a 35 offset and 1.25" drop will not clear either the fender, without rolling or grinding. Also makes contact on the rear shock, under compression. I didn't realize that a 305's sidewall would protrude on a 10.5" wheel as much as it does. I did research but like I said the sidewall buldge was more than I expected.

If I used a 5MM spacer it would just mess with the fender issuse even more. I could put my stock rear spring bushings back in which would give me a 1/2" more height clerance and put it back to the standard Hotchkis drop but I don't think that's gonna be enough, to make much differenace.

I know there are a few guys running 305's on stock fenders. What are your offsets, rim size and drop? Any rubbing

Guess if I want to use the 10.5" wheels, I'm going to have to go with a 295/30 because anything less would be stretched too much.

Now 295 guys, can you tell me what your offsets and drop are? I think I posted a similar question a while aga about 305's but I couldn't find it.

i have 295/30 on a Hotchkis drop

wheels are 19 x 10.5 +22

No pics. I'm taking the wheels off and putting the other set back on tonight.

Is there anything I can do to the suspension that would give me about 1/4" more clearance, like maybe smaller diameter shocks?

What would happen if I ran without any shocks in the rear what would happen? WOuld it blow up? LOL I wonder what would happedn with no shocks though? Hmmm maybe I should take the shocks off:( Ummm no.

On a diffrent note, they look sick as hell. But if they don't fit don't do me much good.

your post was pretty confusing...but let me see if I got it.

Your tires are rubbing against your shock? If that's the case, then you need a more agressive offset. A bandaid fix may be 15mm wheel spacers, or just less camber.

...but girls like em wide ;)

Do you think going with an 295/35 will fit fine? And also how about a 295/35 on a 10 inch wheel with +22?

it should buldge out a lil bit

however you will not rub

check out my pics with the RH's whose are 295/30 on a 19x10 +22

What pics?

what kind of wheels are you running, sounds like it has a huge lip, can you post pics?

Ya it was confusing.

Yes the tire makes contact with the shock, when the suspension compresses/travels more than about 1.5". The outer sidewall of the tire also starts to rub on the fender lip at about the same 1.5" worth of travel.

If I run a 15mm spacer, the tire will stick out that much passed the fender (monster truck style) and all the rolling in the world won't make it clear the fender or be tucked under. A 10mm spacer might be enough so that it wouldn't rub the shock but it would still stick out too far beyond the fender, I think? That would give it a 25 offset.

You're one of the ones running a 305, right? I remember you were looking for replacement tires once and Nitto didn't make your 305's. What is your setup and drop? I could really use your input on this.

Dialing out the camber might help to clear the shock and I don't think it would stick out much closer to the fender but I don't think it would make enough differeance with the shock rub.

I'm running 285's in the rear. Max I ran was 295 DR's.

Did you roll/cut your fenders? If not, I suggest that as your first thing to do, then run some think spacers (don't know if they have 5mm spacers), and you should clear. If you have, then that only means that you are at the max limit of the rear wheel wells, because you are rubbing inside (shock) and outside (fender) at the same tme when your shocks compress. So if that's the case, I can only recommend some stiffer coilover setup, so it wouldn't compress that much.

Chad68 Apr 14, 2007 12:37 AM

I can gain an extra 1/2" of fender clearance by re-installing the stock spring bushings. I wanted to get rid of some excess wheel gap and cut 1/2" off the bushings. Worked great with the 275 setup and no probs at all.

I used the jack to replicate what it would look like with the extra 1/2" of height added back and the tire didn't look like it stuck out much more if any but didn't look like it made much diff. with the inner cleance either but at least that would help with the fender rub.

Think I will play around with some other ideas. There must be a way to get things to clear or else I'm gonna cry LOL.

I guess it was Bubbles that was running the 305/25/20's.

Any idea if I increased the ride height by 1/2" how much if any the inner sidewall would move away from the shiock?

guess I'm going to have to find a protractor and see how many degrees camber this way and that way transaltes into in wheel movement.

Think what I may end up doing is just putting the old 9.5 wheels and 275 tires on until they need to be replaced, then take off the 305's sell them and just get 295's.

+1 one on this. I wouldn't attempt 305s with anything more than +22. Even then that would be suspect in the clearence without help.

Chad68 Apr 14, 2007 01:12 AM

Maybe what I will try before I give up just yet, is to simply put the 1/2" thicker bushings back in. That way the suspension could compress about 2" before anything would start to touch. By putting them back in, it will move my camber back to factory settings, sice I didn't re align it when I swapped bushings.. Then maybe I could tweak the camber in more on top of that. Think that and maybe a 5mm hub centric spacer is about all I can do.

Not really sure how great the added 1/2" wheel gap will look but egh....

Ken@Performance Apr 14, 2007 01:17 AM

Yes Nitrouz is correct u just need to roll your fenders just a tad bit and put a spacer. I am currently running 19x10.5 +28 was +43 but I put a 15mm spacer with a 305/30 series tire and have no rubbing after a little hammering :). Tomorrow I will put on my new rims which are 19x11+24 with the 305's and hope for the best :icon38: . Also I am on coilovers and dropped about a inch with no adjustable camber arms.

BTW here is a pic of my current set-up(sorry I dont have a bigger picture)

In this picture you can kinda see that the rim is still abit inward and not really sticking out of the fender.

Hope this helps a little bit.

So you think if I use a 5mm spacer (which would make my offset 30) and put my ride height back to where it belongs, it will clear the shock ok?

If you run the 305 you will need to roll/cut your fender just to get that extra clearance that will be needed. And if you do decide to roll it I would put a 10mm spacer instead of the 5 just to get those 5mm more clearance from the shock body especially since the tire will flex during hard cornering.

Damn Ken. Love the new look. And the rear bumper. Very nice :D
