Flush Your Stock Wheels

[The Champ]

Tires I'm not so sure, but 18x8 +30-35 would be a good start I'd think. If you look at beastlicks photo above as a reference, a +35 would be about 1mm further in and a 30 would be 4mm more out.

I'm not sure how you're doing your math?

Beastlik's wheels are oe 17's - which have 41.5mm offset. He's got 20mm spacers - so he's sitting at 21.5mm's.

He didn't mention his tire size - but you would need that info to come up with the proper offset to duplicate the tire position.

An inch wider wheel would need 12.5mm less offset to stick out the same amount. Tire width doesn't effect offset, I was only referring to where the face of the wheel will sit.

For reference:

Beastlik's rims are 6.5" wide with a 41.5 offset or 5.35" of BS. Add in the 20mm spacer (.8") and now you are looking at 4.55" or offset of 21.5. Let's assume that Beastlik is running a 225/45/17 tire.

When changing the rim width, the offset required to position the wheel stays the same (21.5), but the amount of BS does change.

So now we want to duplicate that look with an 18x8" wide rim. To put the rim and same width tire into the same position - that would require the same 21.5 mm offset and a 225/40/18" tire (the same section width of 225, but a 40 series profile to generate a tire height that is close (25 compared to 25.1")).

I fully understand that tire width does not change the offset. But a wider tire will affect clearances to suspension parts and the wheelwell. If one was going to use a 245/35/18 (close to the same height) - the tire sidewall now projects out an addtional 10mm on both sides. That may require a different offset to avoid contact with either the body or the suspension.

Your link didn't work, but I'm familiar with this one which is probably similar.

I thought the factory wheel was 7"? Either way, I've only mentioned width and offset, not tires, because tires are a lot easier to change after the fact than wheels.

tainopayute asked:

If I'm planning on upgrading to 18" rims and I also want to get a set of rims that will give me the flush look without having to use spacers or adapters, what size tires and rims should I get?

So if you recommend 18" rims with a specific offset, you should have had a specific tire size in mind.l

Fitment is ALWAYS a combination of rim diameter, width, offset and tire size.

Some tires are more expensive than the rims - so bottom line - you want to get both right.

As far as the OE rim sizes and offsets - we have it permanently stickied here:

I ended up with 20mm H&R Spacers. Probably could have safely gone with their 22mm, but this still looks nice. I think this look is how the car should have come from the factory.

40k miles on my adaptecs now. Not single problem with them. An additional benefit is that the scrub radius changed in such a way that steering feel got heavier with more road feel... something the non-RS cars desperately need.

Anyone wants a set for 200, I'll ship them ASAP! I'm jobless [emoji85]

what kind of long term wear and tear can someone expect to get from running spacers on our sonics?

 

[Natesriv]

I've been on 5mm's (wider aftermarket wheels than stock)...no issues. My spacers keep the wheel hub centric, so those forces are still where they should be. I think the larger spacers have hubs in them as well, so the wheels remain centered... The main forces would be on the OEM hub/spacer interface and the bolts holding them in place. It's really just a longer lever and at 20mm's it's not that large.. So if using spacers which require bolting into the OEM hub, don't skimp on price...

Also, with bolts for the spacers or wheels, the more turns you can get to bolt them down, the better

My set is adaptec, and the heavier road feel of night and day!!! It feels like a car, nota go cart anymore.
