Question on rear tire-to-strut mount clearance

[Rahul718]

Hey all,

Just need a sanity check. I recently moved to all seasons on my ZCP, so even though I retained the same OEM size, it turned out that the tire width is quite a bit wider than the Pilot Super Sports it replaced. As a result, it is rubbing on the outside in the fronts. I had a scare where I thought the tires were rubbing on the insides with the strut perch, but I have about a 1 finger gap clearance.

My question is, how does the rear inner clearance look? I'm not too familiar with the rear suspension and the path of travel of the tire relative to the strut. Does it look like I could be at risk of rubbing the inside against any of the strut components? I don't think so and the clearance looks plentiful, with the tire not being in the path of anything, but just wanted to confirm with you guys here.

Tire and strut mount are both circled.

Thanks

bump

4 month bump. Anyone?

[jfritz27]

That's plenty of room to the strut

Nice, thanks for that feedback! Looked adequate to me but I wasn’t sure how much the wheel tilts inwards when going over bumps, dips, etc

The rear tire camber does increase with compression but it’s still only a small fraction of an inch. The rear shock also sits further inboard relative to the front strut’s position. So, as jfritz27 stated above, you have plenty of clearance between the rear shock and rear tire tread/sidewall.

Thanks for the confirmation

Got around to taking a picture with measurement as a reference point. It’s showing 2.75” from the inner wheel lip to strut, so assume minus 1” for additional tire width for safe measure. That’s 1.75” clearance with the suspension loaded. I’m curious… would any amount of wheel alignments (OE spec, nothing custom) drastically change this rear clearance, or would it more or less maintain this much of clearance?

Thanks

Camber is the rear alignment setting that will alter wheel clearance the most but it’s still relatively small. If the tire diameter is ~27” then a 1 deg increase in negative camber would move the top of the wheel inward ~0.235”.

M3SQRD thanks for the reply.

I didn’t know there was a camber to mm conversion. Good to know though!

Really appreciate your knowledge in this area!
