widest tire wheel combo 19 and 20" ZL1 1LE

DDFast · 08-19-2019, 06:39 PM

ok if this has been answered on a 1LE please direct me to the post, I've seen a couple but most are SS or ZL1 I know we have a little more clearance because of the DSSV.

Im going full custom wheels so any size and offset is available.

Thanks

We fit a 355 V720 ACR tire on the back of the stock wheels on our ZLE. Required some "finessing" to get them to work.

What in your opinion would be the largest setup for 20", I'm glad the the OE wheels fit a 355 as those will be my track setup and want 20's for the street for more visual stance

Did you go wider up front? It would seem like going wider in the rear and not the front could cause handling changes (see understeer). Did you have to make any suspension changes to counteract any extra rear traction vs front (swaybar adjustment)?

We didn't go wider up front, but one guy I know put 325 GY3Rs up front running MCS coilovers (doesn't fit with stock suspension).

Car handles fine with 305/355 combo. No suspension changes. Had to add adjustable toe rod arms in the back to get enough camber to tuck the tires under the fender.

Do you think that a 345 would require the same adjustment?

I’ll be trying a 325/30/20. I’m a little nervous as there might be a little poke with the off set on the new wheels. I think it’ll look great but concerned about the upward wheel
travel.
