OK, I freely admit I don't know what the scoop is with the offet on wheels. I know that the stock offset of the rear wheels on my SRT-6 is ET 22 (+22mm). I pulled them and looked! (I even have pictures)

I went to my local tire/wheel specialty center to see if they could find some wheels that I wanted for my drag tires. To make a long story short, the guy told me that putting a 35 offset wheel on a car designed for a 22mm offset is OK. That nothing bad will happen. I know that clearance with my tires is NOT a problem. I'm jsut worried about the offset.

Is that a load of crap because he wants to sell me wheels or what?

How much of an offset variance is OK?

 

I have 25 in the rear on mine. Not sure about 35, seems a bit much.

 

mine are 20 and fit perfect, 35 may need a spacer which i would avoid if i was you

 

I thought you had 30s. Or did I read that wrong?

 

I had a typo before. My invoice says 25 on the rear and 32 up front; however, I think this is actually the typo. I'm pretty sure that the true offset is 30 because 25 isn't offered in the 20 x 10 size according to Mandrus.

 

OK, maybe someone can point me in the right direction on this too:
I have 35mm and 33mm offset wheels for the back (two different sets, one for racing, one for driving). If I don't use spacers, I need shorted wheel studs (bolts). Where do you get them? And how would I know what to order?

 

I have a set of short bolts for sale in the for sale section. Only 16 lugs though, discount tire direct sent me the 4 lug set instead of the 5 lug set. Do you just need them for the rear wheels? if so that would be what you need.

 

Keep in mind that the difference between 20mm and 35mm is a fraction of an inch. The 35mm will fit, the wheel and tire will just be “tucked in” closer to the inner wheel well. The lower the number, the further out the rim is “pushed” from the mounting surface in most cases. I like the look of the wheel being pushed out myself, but if you go on Discount Tires website and pull up fitment for our cars, you will find 20mm, 25mm and 35mm. They all will fit, they just will fit differently. I hope this helps.

 

Thanks Photoman. I posted over in the FS thread.

BlkFin: yeah, I understand the fitment will be pushed in compared to the stock setup. I'm not worried about clearances. As you said 11mm is less than 1/2 an inch. I'm sure it will clear. I'm more concerned with the change as it affects the ball joints and suspension geometry. Also I'm concerned that the longer lug bolts will screw too far into the wheel hub and cause problems. I think others have run into this but I can't remember who.

 

OK, I found this through the SEARCH function but I'm still dumb about the answer. I'm looking at wheels from tire rack and it says 32 offset for fronts and 36 offset for rears. Do I understand correctly that this will tuck the wheels closer inside the wheel wells? If this is the case, do I get back to a normal stance by getting spacers to push the wheels back out to manufacture specs?

Man there is alot of stuff to this car thing.

 

You're right on the money Punkin. The factory offset for the rears is 22mm, so your 36mm offset wheels would push the wheel/tire 14mm in towards the center of the car. So 15mm spacers would set you almost exactly back to factory spec.

Since the factory spec in the front is 35mm offset, then the 32mm offset wheels you're getting will be pushed out 3mm compared to factory spec. 3mm is so small, you don't need to do anything for them.

Before you get spacers for the rears, you'll want to do some reading up on them. Some say they're great, some say they bad for your car. My take on it is as long as you've got clearance for the wheel/tire within the wheel well - AND - you're going with a LARGER offset, why mess with spacers? 15mm is a little more than 1/2 an inch. I doubt you'll have any clearance issues - assuming you're not also going with wider wheels and tires. So why spend the money on spacers?

 

1. If your wheels are the same width as stock, then the offset should be as close to stock to keep the wheels from being pulled in or pushed out.

2. Spacers are fine IF they are hub-centric spacers. Anything less is putting the load on the lug bolts.

3. If your wheels are wider than stock, then you have to figure a whole new offset to make sure your rims are still centered compared to the stock ones without pushing them out from the center of the car too much. This could lead to rubbing the edges of the fender and possibly cutting into the edge of your tires.

4. Wider wheels should be complimented by wider tires. Not always, but it looks a little strange on a wheel that is wider to have the stock width tires. I know I had stock size tires on my rims and they were a half inch wider in the front and one inch wider in the rear. Needless to say the tires seemed really narrow in comparison.

Lastly, examining all these things together with your wheel styles will allow you to pick the correct combination and spacers (if needed) ahead of time.

Just curious, what are the specifications on the wheels and tires you are considering?

 

do u have any pic to show,,,, I do, I have 17" x9" wide with 40 offset as long as you have a lip on the rim it will fit, here are the pic.

and i use a 1" lug bolt

mounted on the car..

 

I have a 2" lip on the rin with the 40 offset = fit.

 

Currently, I'm running

18x8.0 Nogaro Silver 5x112 Bolt pattern 32mm offset. Yokohama Advan Sport 245/35R18
19x9.5 Nogaro Silver 5x112 Bolt pattern 35mm offset. Yokohama Advan Sport 295/30R19

Now, that being said... I currently have a 7 or 8 mm spacer on the rear, but I think I'll be replacing it with a 12mm and moving the 7 or 8 mm to the front as I had some small rubbing issues, but nothing severe.

I'll probably be going to Vredstein Sessanta Ultrac tires when I change next.

Cheers!

 

Thanks for the info. The wheels I'm looking at are the same size as stock but with a 32 front and 36 rear offset. I am going to suppose that tire rack will have and will sell hub centric spacers to maintain the origional specs.
