What tires are these, if you don't mind me asking. (manufacturer and size)?

Thank you.

Toyo R888

[EDFHOBBIES]

toyo R888.. if he's stock rim 20s 285 30 20 most likely..

they have 285 30, 285 35s and 305 35s (watch harness rubbing consider moving it)

20s

255/35ZR20(93Y) not worth your time
285/30ZR20(95Y) no problemas
285/35ZR20(100Y) probably ok with harness
305/35ZR20(104Y) Move wire harness
315/30ZR20(101Y) Run Spacer

you have the 1le you can run the 305 35 20 and 285 30 20 Just need to relocate the harness in the fender well on drivers side..

if you don't want to mess with it the 5gen 1le guys usually ran 285 all around and found that on the back the 285 gave them more surface area on the wide rim.

Thank you King and Ed. I have to replace both back tires. I am running 285-30-20ZR in front and 305-30-20ZR in the back.

I like the different tire sizes for front and back. No reason, just personal preference. Any other recommendations?

Thanks, this is my next tire, the only thing I'm still thinking about is should I widen a set of stock rims and if so should I do 10" wide, 10.5" wide or 11" wide. I kind of want a narrow rim so 10.5 and 315 / 30 R 20, suggestion on width and back spacing appreciated.

They are Toyo R888R the newer version of the R888. 305/35/20, my wheels get here today I’ll send pictures. 11” rear 10” up front, very aggressive offsets.

[MIAMI2SSRS]

Thank you, sir.

We have them on my buddies 900 wheel horsepower c6 , and they hold all the way in second gear without even warming them.
But he is also lucky enough to run 345’s

[Slidewayz-Jones]

The things change color it seems. I posted the offsets for you guys as well

Do you think that would be any rubbing issues with the 305-35-20 tires on the 11" wheels in the back?

Nice wheels!!

Cool. I am looking to buy two tires for the back wheels (MRR 1LE wheels 20 x 11). So was curious to find out if the 305x35x20 tires would causing rubbing issues.

Thank you, sir.

So the car is at redline Motorsports awaiting the tune. I’m going to start with a pump gas tune for a short time. Reason being I’m coming up with a few different ideas on fuel support.

[oldman]

I was on the fuel debate for a long time. I finally went to a fully upgrade DI, able to run E85.

Within reason 93, E85 and Meth will all put out the around the same HP at stoi, the slight advantage of the alcohol is there is just more liquid being injected leading to more expansion gasses. E85 has a higher max rich mixture than fuel, meaning there is more liquid to not only expand, it also means a lot more cooling of the piston during the compression cycle where the phase change takes place. It is the phase change that absorbs heat.

Now meth has such a high rich max power A/F ratio, you can literally pour it into an engine and continue to make power. Also very insensitive to cylinder variance and atomization compared to gas. A perfect choice IMO for PD. That said for a centri, I would still go to 8 points on a high ram as the stock manifold is not made to flow liquid. Call it OCD. The second issue is what if something goes wrong with the secondary injection, it can be as simple as running out of fluid.

Given the added complexity of meth injection, it was just easier to go with a DI system. The cheapest upgrades are in order: Lt4 injectors, cam lobe, LT4 HPFP, LPE HPFP, lt 4 based 30% injectors FIC GDI, "52%" more KDI injectors. Not including labor. It would be interesting to see what a LPE HPFP, and KDI injectors would support on E85 with the stock fuel lobe, this would be the max "bolt on" that can be done for $1600 and $4250.
