I just copied and pasted it from the wheels and tires thread as i was not getting any response. I dont think many people get on that part of the forum so I figured I would post in the GS section.

I have a 99 GS300 with 225/35/19 tires up front. I was wondering if I can go 235/35/19? I see most guys here on the forum go with 225 on 19" wheel. I dont like the stretch tire look and it just looks unsafe IMO. Why do most GS guys go 225 instead of 235?

Current set up:
19x8.5 offset 35. ADR wheels - Similar to SSR GT3 wheels
225/35/19 tires on Stock suspsension.

 

I actually have the same question. And I don't mean to thread jack but can anyone clarify what it means when a tire says 81W vs 91W?

 

What makes you think a 235-35-19 wouldn't work on your 19x8.5?

An 8.5" rim will measure between 9.25-9.5" from lip to lip (some manufacturers have 0.5" lips while others have 0.375" lips)

A 235mm tire measures 9.25"

A 235-245mm tire is optimal for an 8.5" rim. You can't get anymore square/safe.

 

You'll be fine.

 

81W and 91W are speed ratings. Tells you how fast you can go with those tires. It really matters on the letter tho not the number.

 

i have 235/35/19 on the fronts.....im on 19x8" up front though and 8.5 on the rear

maybe cause 19" tires dont go on 18" rims.....

 

Thank you for the response. I just dont see many guys running a 235 tire on the GS for some reason.

 

i was thinking doing the same but i really dont have any clue on wheels.

 

lol............

 

Thanks for catching the error, lol.

But ya, a 235mm tire will be perfect on your 8.5" wide rim.

 

oops i mistyped earlier....i meant to type i AM running a 235/35/19 up front but i am on 19x8 up front not the 8.5 u asked about.

 

Ahh thats good. It currently looks stretched on the front wheel and I feel I may damage the lip of the wheels when I turn. There's already some curb rash on the wheel already but I'm getting those refinished then put the 235s on.

Also if there is any DFW guys on here that need a place to go get their wheels redone, just PM me.

Before:


After:

 

19x9 +35, 235/35/19 np for me

 

81W and 91W is the load index and speed rating.

81/91 = load index.

81 = 1019 lbs
91 = 1356 lbs

W = Speed rating
W = 165 mph MAX. anything over can/will/might heat up the sidewalls too much and BOOM.

 

19x8.5 offset 35

^ same specs as my wheels before the spacers.

I started with 245/35/19s. Dunlops are a slight stretch in that size.

Now I'm ruining 255/35/19 dunlops again. Side walls are squared off with the wheel and they look great.
