Oh well nice looking setup :tup:

You're answering the question with ignorance! I don't care if its worked for you or if you like it. You running that thin of a tire on that thick of a wheel is like playing Russian Roulette. You wouldn't tell a member to turbo the car and run 20psi with stock injectors and he doesn't need a tune would you? You wouldn't start telling people the torque spec of the lugs is 5ft/lbs would you? I don't care how it looks (looks retarded always), you need to give warning that's it's not recommended and possibly unsafe. There are a ton of newbs here who buy into **** that don't understand jack. Like I said, do it right or not at all. That's how I feel, live with it.

I definitely agree with the idea that a lot of people speak rubbish online and its our duty to try to sift with best of our judgements, using personal experience and basic physics even. At the end of the day, I value personal real unbiased experience over most people's "theoretical" experience, with one disclaimer: theres always those people that rarely say their stuff sucks because they bought it. I am not im the market for "best bangs for the buck". Buying this Z was a niche market choice and i believe we owe it to ourselves to value whats truly value added over whats a good deal.


However i think the examples of 5ft/lbs of torque are a little extreme. I agree, gear suggestions should always be followed with an explanation (helps noobs like me learn!).

In agreement with the above, I do know for the majority of options that a lot of street tires and ESPECIALLY most all season tires would be unadvisable with a 275/35/19 on a 10.5" width tire.

In agreement with the other person (again i really appreciate the pictures and feedback).I do know from personal experience at the tracks ive been to that a lot of sticky track tires and specifically some michelin tires and the yokohama neovas run especially wide and arent as stretched. My guess is because they are built with a much harder shoulder and sidewall.

For reference purposes my 285/35/19 in advan sport is a ~10.2" tread width on a 10.5" but an advan neova in 275/35/19 is a ~10.6". Another good example is my coworkers e55 amg. His 265/35 pilot cups ran wider than his new 285/35 hankook v12s.



Again i am not discrediting either statement. I am eternally grateful for feedback from both of you guys because it helps me see BOTH sides of the equation. Happy tuesday and keep the suggestions coming! :)

I don't always agree with SynoLimit, but when I do, it's on issues of safety.

Running your tires this way delves a wee too bit much into ricer turf for me.

Besides, why waste your money on a tire you will never use 20% of. This tire is designed to operate at 165-200 degrees on a race track. For one, it's a complete waste of money.

Secondly, R-888's are not even really safe for street driving especially once it drops below 50 degrees. They are a frigging r-compound race tire that is legal to drive on the street to a track simply because it has some grooves to vent water.

I understand style and taste differences, people hate my plasti dipped hood-bra. But it is functional and I like the way it looks personally. I won't comment on the super stretched look but I don't personally like. The difference though is that your tire can explode and kill you. My plastidip-bra is just going to piss off my friend martin82 at the race track.

There are other good looking tires that fit whomever's wheel correctly. Buy those ones instead.

Who said the r888s were for street driving? They're for track days I do here and there. Otherwise I use the stock rays (or another car) year round. And they are absolutely not super stretched. Using the ideal tire/rim width calculator (Car Bibles : The Wheel and Tyre Bible Page 4 of 4) the 275/40r18 can go on anywhere from a 9-10.5in rim. Not saying 10.5 is a perfect size but it's not stretching a 255 onto an 11in rim. Still feel as if you're blowing it out of proportion.

You guys would kill me for having a 255 on a 10.5 wheel, lol.

That was on my Genesis Coupe. I won't be replicating that, since I've got a Magma Red Z I have to stick to a more classy look. Although I wish I could do a little tuner style with it.

As for safety, honestly guys unless you're driving the car around corners way above the speed limits running a stretched tire is not a concern for street use if it's nothing to outlandish. As for the track you must run the correct tire width or it will lower your lap times. By the same token too wide is also detrimental.

I thought for some reason you had 10.5 front. And TY for telling me they are track day tires. Personally I really like the way your car looks. What kind of setup do you have?

I want to say.... That he has the same or similar wheel setup to martin's with slightly different offsets. I may be wrong though. It is a 10.5" front from my understanding. Martin is one of the main guys that actually inspired me and helped me pick my 19x10.5"+30 square setup.

I ran a 245 on a 9 inch rim vs 8 inch and it was faster, better turn in, maximizes tire contact patch. I raced with this setup for over a year, many autox racers stretch tires.

I do have 10.5" in the front and want to go with a wider tire setup in the future. I did shortchange the size a bit but it still felt great on the track and from the wear on the tire it looks as if I've maximized the contact patch just fine. Again I am NOT saying this is ideal or that everyone should run this but simply that this is MY experience with MY setup thus far. The biggest difference I've noticed is that with the wider front tire vs the stock 245 the turn in is fantastic. Felt like I had to fight it a bit when I was autocrossing on the RE050's.

I realllllllllllllllly want to go with a 295/30/19 (or even a 305/30/19 MUHAHA jk) on the front and rears with my new square setup. I feel like that would be square enough on the wheels and short enough on top to minimize inner fender rubbing. I'm just worried about "inner suspension/brake" clearance as it says on the rim and tires calculator online. I have no idea what that means and how that affects the front.

10.5 up front is what I run with 285's. It is a quick easy and relatively inexpensive way to cure understeer. I am not sure it is all that Ideal myself though since it is inadvertently going to affect acceleration. I have RPF01's which are +15, and once I put a suspension on, I may have to roll my fenders a bit.

There are other ways to deal with understeer once your suspension is tunable. But for a quick dirty way to cure it, square setup on 285's works great.

It does. And no need to go above 9.5" if you're going 285 square. Keep the weight down and no stretching if tire brand changes.

wait what? :confused:

What are confused about :confused:
