Tire size question for CV05

TPC1372 — Sun, 24 May 2026 04:18:14 GMT

Greetings,

2000 Camaro SS. I am looking to get new tires on my 18inch CV05 wheels. I am looking at getting michelin PS4S. my research suggests. Fronts 255/40r18 and Rears 285/35r18.

Front wheels18x9.5+54 offset about 7.38" backspacing
Rear wheels 18x10.5+56 offset about 7.9" backspacing

Will they look ok with that profile and will there be any rubbing? Do I need spacers?

Viking front coilovers and rear koni adjust adjustable shocks eibach lowering springs.

Any advice would be awesome. Thank you.

Stuffed my 12.5� rims and 335 tires on the back of my WS6.

Wasn�t too hard. They�re tucked in nicely. No rubbing the fender lip on any bumps yet.

Did it mainly for looks. But traction is much better.

Opinions�..Comments��?

Weld Rims not sitting right

Finally after 5 years in hibernation I decided to revive the my 02 Z28 and dip my toes back into the car game. One of the first refreshment mods was to swap rims/tires for new ones.
OFF: Z06 rims 18x10.5 w/ 295/35r/ 18 on the rears and 17 x 9 w/ 275 40R/17 on the fronts.

ON: Weld Ventura's 18"x11" +43 offset w/ 315 30 18 on the rears and 18x10 w/ 295/30R/18

Slapped them on and checked for clearance and rubbing, stood back in awe at the beauty and then right before leaving noticed something off. The left rear wheel is poking out farther than the right rear tire (I was expecting little protrusion on both sides but not a mismatch). I double checked the rims to make sure I wasn't sent mismatched offsets or tire sizes. Everything matches so is it possibly the rear end isn't centered? It has an aftermarket adjustable pan hard bar w/ Sportlines from when I bought the car, could the panhard bar come out of wack over time or from donuts and hard driving? I'm mainly confused because the Z06's didn't seem to be mismatched but maybe because they were slightly smaller and tucked into the fender more I didn't notice. I started looking at pictures of the Z06 rims before and it seems like the left wheel is closer the fender than the right wheel but maybe you guys have a more keen eye. Also it has a spool (on the to do list to swap it) so I don't know if that constant locking could force the rear end out of center? Any advice appreciated.

2001 Camaro SS rims

I was wondering if these rims are factory. Im not sure if they are aftermarket or off of a 99 car or something. One of the center caps broke and I was wondering where to look for replacements. Thanks.

whats needed for 18x10.5 c5 z06 wheels on all 4 corners?

Tires on the wheels now are a 275/35/18 but will prob end up going 295/40 or 295/30. Car is lowered (koni yellows on bmr springs).

From what if found by searching on here, fronts really arent much of an issues. Maybe alittle running on full turn.

Rears is where I see all kinds of answers. I know ill have to do BFH mod on the inside parts. Bump stops are the main confusion. im not cutting mine, but I can grind them down some and see if that helps. worse case I can always add a 5mm (or around there) spacer. A fender roller im good with doing as well.

My question with that is, it seems like with the rear suspension at full drop,(as im the car is up on a lift) will the wheels rub the bump stop reguardless? But under normal driving id be fine? Or i need to make sure there is clearance from the bump stops no matter what.
