CT5-V 5BW new tire time - discussion

[AZHEAT]

The consensus obviously is to stick with TPC spec OEM, however I would like a better option as well. I don’t deal with cooler temperature issues where I live and it rarely rains, so I’m looking for warm weather performance options besides the Cup 2 as well. I had 888Rs on a previous car with the LT4, so I know that would solve my problem but I’m not willing to deal with the noise. They were even louder than I expected.

I know many forum members run their cars and do track time with OEM tires and are very happy and I am too with some degree of traction/stability control on (like the recommended settings when at Spring Mountain). My frustration comes when traction control is off and I want to run through the gears. I realize the ask with the level of power and tire size limitation, but I would like to think we can do a bit better.

I’ve decided I will most likely try to run Cup 2 in the rear and OEM TPC spec in the front. Not engineered for that, but I have to think it may work for my purposes.

I hadn't looked at Tire Rack in a couple of months but there seem to be more sticky choices than before, including an updated version of the BFG Rival that might be interesting. I'm happy with my 2nd set of TPC-spec tires but will probably try something different next time.

I ordered a set of Nitto Invo tires to use as all seasons. It gets cold where I spend half my time up in the Sierra Nevadas. I’ve woken up to snow on the ground in August even.

I’ve also been told that the Nitto NT555 is a great tire that grips like a mofo… but I’ve never used em personally.

The 555R is not that great but the 555R2 is fantastic.

Several of my local guys run Nittos 555 on their Camaros. Im about to replace stock Goodyear garbage on my 2018 2SS with the Nittos as well. So don't know personally as yet but I trust the guys running them.

Anybody ever run on Nitto tires? Reviews say there ultra quiet and stick like glue. Just curious if anyone here has real world experience.

The Nitto 555G2 is pretty average at best, not even close to the Michelin PS4S. The Nitto 555R is an average drag radial, not very impressive honestly.The Nitto 555R2 is a VERY good drag radial for a street driven car, the sidewall is actually stiff enough that the car will handle pretty good with them too, only downside is they're not good in the rain and they don't last that long before needing replacing.

Somebody posted this in the Media Dumps thread a few days ago:

I'd be willing to try one of the top finishers. I'm happy with everything on the stock tires with one big exception: as they have aged (2.5yrs and 18k on mine) they have clearly lost a lot of grip compared to when they were new. And I don't drive them in the cold, haven't tracked, etc. My hunch is the Cup 2 compound in the TPC version heat cycles out long before the tire wears out. I've noticed far worse dry traction since probably 12k miles.

Need a little advice, I have a CT % BW, with precision pack... Car has about 2,100 miles, my back left tire has a very slow leak, I'm pretty sure I saw an article that if you replace 1 tire on the car, that all 4 have to be replaced? Is this true ?

No. You are thinking of the 4wd thing. Its a good idea to keep the circumference of the rears closer to each other than not, because of the dif, but irrelevant on the front.

If you go to the dealer, they will be compelled to replace all 4. You as an individual are free to do whatever you feel is sensible; such as just replace both rears on your own, or plug/patch the leak.

Thread 'V8V Precision Package and Q2Y 19” Michelin Pilot Sport Cup 2 R tires signed acknowledgment'

Mar 18, 2025

Not sure if this has already been covered. Cadillac is requiring dealers to have customers sign a customer acknowledgement form when they take delivery of the V8V Precision Package and Q2Y 19” Michelin Pilot Sport Cup 2 R tires. It references the need to replace all 4 tires if one needs to be replaced. I figured it was good info for anyone who is placing an order, as it probably won't come up until doing the final paperwork.

There’s also a possibility that your dealer may not know or care about the situation but best bet is be prepared for them to require all 4 to be replaced if you go there.

unless youve burned up the tires at 2100 miles, which im guessing you did not. you can replace one tire or do a patch

Exactly. I damn sure wouldn't replace all 4 tires at 2100 miles. In fact I just had to replace one of my front tires on mine since I noticed a large gash in the sidewall. My car has 8K miles on it, I certainly didn't replace all 4.

First question is if its fixable. Can it be patched or plugged? Id fix it first before anything else.

If you decide to replace, depends on which tire it is. Is it the cup2s or the PS4 tires. If cup2s, I'd replace the pair since 2,100 on cup2 in the rear, it would already have some wear on it. Barely expect to get 8K out of cup2s.
