Post Era RE-11s, Sports Rays and 305 tires
 

Hopefully somebody--or better yet several people--will have an answer(s) to my question. I've dug through numerous threads (e.g. "will it fit", "370z meaty tire thread" et al.) looking for the solution but to no avail.

I am trying to run a 305 rear tire on stock, sport rims. When the RE-11's were in production this was a no-brainer:

305/30R19 (rear) & 265/35R19 (front), or 275's etc.

Obviously, the RE-11's are damn near impossible to come by now. So my question is, are any guys/gals running a different 305 rear tire on stock sport rims? If you are, what are the exact tires you're using?

I've been PM'ing several users who I thought had 305's on the 10" sport rim width but it seems most people were actually on the Nismo (10.5" wide inner rim). I believe Rumblefish has the stock sport rims and is running S-04's but I couldn't find anyone else or verify that he had no issues. Another user I spoke too thought someone else was running PSS's in that combo but had issues and blew out a tire.

Can those running 305's on stock 19" Rays with the 10" inner rim chime in and maybe post a pic or two with your setup?

Additionally, I just wanted to add I am on stock suspension, no spacers, and have the sports brake package (Akebono calipers). If you had rubbing issues or had to change anything up with your 305 tires on sports 10" rims please comment on that too as it will be helpful.

I have talked to several users running 295's without issue and ultimately I may have to give in and go that route. I'd like to make Rusty proud though and go as meaty as I can on the rears, LOL.

Hopefully this new thread will help out any other users in the same boat and solve their frustration with reading hundreds of pages only to come up disappointed and/or more confused.

I am running 305/35/19 on Nismo wheels, so the width is the same with just a bit taller side wall. It looks much better than 30 profile. 305/35/19 is not cheap and also hard to find.

Look into RE-71's. The only problem is the widest they have is a 305.

That 35 profile looks great with those tires and I like your Nismo rims. Correct me if I am wrong, but wouldn't your inner rim width on that Nismo still be 10.5" though? At 10" with the sport rim I am going to have a hard time pinching those tires I think to fit. If yours is 10" wide then definitely game on!

I dont see much diff in 305/30 vs 305/35 on Sports rim. Nismo rear rims are 10.5 and could comfortably fit 315s or 325.

I just wanted to post an update. I ended up taking a gamble and just pulling the trigger on some new tires. I really wanted the PS4s but wasn't entirely sure they would fit. I had a good feeling S-04's, PSS, or V12's would fit based on prior posts (albeit years and years old).

The PSS had several specific options for Porsche, Mercedes, et al. and I wasn't sure what to go with while the Hankook's seemed to have pretty bad feedback from this forum so I opted for Bridgestone. I couldn't find any stock rims running the RE71's either so I was on the fence about going all in with them.

I ended up getting Bridgestone Potenza S-04's for my 19x9 and 19x10 Sports rims in these sizes respectively:

265/35 & 305/30

The front tires fit like a glove and the rears also fit well although the rim is slightly engulfed by the tire (providing a little extra protection against curb rash). The height--26.3--is very close to OEM. I've had no rub issues on my stock suspension.

To be fair, I've had a pretty limited amount of time driving on them so as the months go on I'll provide more updates.

So far though I am VERY pleased. The tires grip great and with FI my OG stock rear 265's were getting clobbered by the horsepower. These definitely hold it a lot better and give me more traction and confidence.

Here are a few pics for now:

I ran 305/30 on Sport wheels no problem V12's.
