Inokinetic vs. 225/40

Why take chances? Do both.

225/40 wins this battle. Get PPF.

Both don’t hurt but if any rock makes it past the mud guard it’s flying with force almost perpendicular to the car. The air could push it back but realistically the car will have cleared it.

PPF is never a bad thing though.

PPF is not a magical solution to prevent paint damage from rocks. Some rock hits can cut into it and still chip the paint beneath. I have several on mine. The chip guards prevent some rocks rocks from hitting the paint. Get both but none are a 100% solution. Better than none at all though. The only solution to chipping paint is not to drive it, but that’s really no solution at all.

Back in the day, it was called patina

LOL - this is how I look at everything that I own. I maintain them responsibly, but not obsessively. I do have the stone guards though, and anything that gets pasts them does seem to miss the sides. I run 215/40's on the front. I may put a small rubber extension on the stone guards. My Michelin Pilot Sport Cup 2's have wide shoulders, and I do have weird chips that show up in odd places though. But I drive mine every day and expect things to happen. I've had rocks cut right through the PPF, and chip the paint. I don't follow anyone to closely and that seems to help. But I just enjoy my car and don't worry too much about it.

FYI the chip guard is detached in that pic, and not in its original further-outward position.

I can probably offer some good experience to this discussion. Zoom in on these pics. The rockers were painted, the doors and quarters were not. You can only imagine what the original condition of the rockers looked like. They were brutal.

I’ve had 225s and chip guards for years, but only PPF on the front hood and fenders. Once the rockers were painted it became clear how far gone everything else was. So now I’ve had the whole car painted and it’s being wrapped completely.

The rockers really get worked over, but there is minimal damage higher up with the oem 205's. This is on a RA car with 2.5k miles. PPF on hood and front bumper with chip guards now in place, but that's it. Looks like that isn't going to cut it to avoid future pics like yours.
Are you saying the wider tires are responsible for marking higher up on the door panels? I had intended to PPF rockers only.

Wider tires, over -2 degrees front camber, lots of on-track driving, and 70K kms.

That’ll do it. 😁

I’m running 235 slicks up front and track my car regularly. I did probably 4 weekends before getting the guards and I had chips all the way up my door to the mirror base, and the rockers were beat up pretty bad.

The chip guards made a world of difference, especially with the rocks and slag that the slicks pick up. Even if your extra 10mm means a rock or two gets past, it’ll divert 99% of the debris and, more importantly, the debris with the worst angle to your paint. I highly recommend the flaps to anyone who runs sticky tires. They are low cost insurance.
