Cadillac CTS-V - Tires Question

Lowered H&R and MM spacers.

265/35-18 or 255/35-18 or 255/40-18 (all 4 corners)

Would I be safe with either of them?

I'm unsure on clearance with a tire larger then 245 on the front end. Maybe search it up? On my CTS, I had tires larger then 245 and was having slight rubbing issues on hard turns. Not a V, but very very similar front end and frame structure.

If your looking for a square setup I would stick to sizes closer to stock to keep your speedometer somewhat accurate so 265/40, 255/40, 275/35 would be good options if you want more tire than stock. I wouldn't go much shorter than an inch or so from stock imho and if staggering keep max of 3% difference between front and back.

dudes have run 265/35-18 in the past and rubbed pretty bad in the front at lock. at stock ride height, tore up the fender liner if i remember correctly. a bunch of them got a good deal on BFGz in that size.. it was on the other fourms a long while back like... 07-08

i would go with 255z in the front.. honestly my fenderliners show signs of rubbing with the 245z at stock height so dont think there is much room for play

This right here...since you are lowered, i would not go any wider then the 255 in front.

I am lowered the same way you are, and there is not much room the front for wider then a 255. I have 245/45 up front and 275/40 out back, and the 275/40 rub a little in the back.

I had 265/40 bfg kds on all 4 wheels at stock ride height (minus the Maggie drop is 1/2") and I didn't have any rubbing at all. They wouldn't work on a lowered car but I know someone that ran 255/40 rt-615s with ground control and didn't have issues. 255/35 should definitely work, but I haven't personally tried it.

Rub the fender liner?

What about Front 245/40 and Rear 275/40?

i never rub in the front...the rub was in the rear, and it was the side wall catching the inside fender lip. it would only rub on bump or under moderate to heavy acceleration.

245/40 front and 275/40 rears will be fine...you will just have to keep an eye out for the rub out back.

I always preferred running stock sized tires. 245/45 had a good sidewall when lowered. Get a good compound tire and it'll hook.

FML...haha...that sounds fucked up.

I should have added a "no homo" or "so to speak" with that statement.

Phew. I'm glad you took that well--you never know if people can appreciate the humor in an intentional misinterpretation of something they say. :thumb:
