Drivers who have or have had Toyo R888R tires
I am waiting on my HPFP do arrive, as have it installed along with an E85 tune and possibly meth just for extra cooling. Once I have attained my power goal, it will be time to upgrade the tires.
Regarding tire size how about going with 325/35/20 on the rear? If I have H&R’s, will it cause rubbing? I just thought a bit of a larger side wall can add a bit of cushion in potholes/cracks etc, and fill up the wheel well a bit more which are two nice benefits.
Any thoughts?












having said that. The trade off isn’t really worth it. When you’re on a forum it’s good “if you can do this as a general rule” is to give the person asking the question the best answer forward. The R888R is not a good tire for cars above 3500lbs. It struggles with heavier cars due to the thin sidewall.”which makes it great for launches” It’s not great on the track, it’s wet weather handling is poor, it’s very noisy, it wears fast, but in a straight line it’s better than the others. Now I like to think I gave him as much info as possible than just saying the tire is good for launches. He needs to know the good and bad of the tire in question.
I don't track my car. I rarely take it on long trips (I trailer it to events). My fun is mostly short runs on weekends and evenings. I join friends for drag strip days and I have another friend who shuts down his airport a couple times a year so we can do 1/2 mile speed runs. I have a stage one tune so I have more torque than I can manage. So, this might be the tire I want.
If it isn't, I'll craigslist them and get different tires. No biggie, and I enjoy experimenting.

The installer advised me not to accelerate sharply for 2 days to allow the wheel mounting lubricant to dry, or else I could spin the wheels within the tires and throw off the balance. That was a new one for me but it makes sense. So after I'm able to drive it at 100% I'll report again.
Also, the 325 30/20 fits perfectly even though the car comes with 305 30/20. Toyo recommends this size because they do not make a 305, and the 315 does not have sufficient weight rating.
