So as you’ve guessed it I have a beautiful 5th gen Celica and I’ve only just realized that the tires are 17in while the rims are 18in... how is this even possible?
The two do not fit. A 17" tire will become useless on a 18" rims because it will be pulled apart trying to mount it. Something is wonky here. My bet is the rims is a 17" since the tire is not destroyed during mounting. Seems rs2 does make 17" rims.
Yeah that's not possible due to physics, so not much arguing that if you know you have 17" tires, then you've definitely got 17" rims.
@mod_man
Just measured the rims and they are in fact 18in. The rims also only come in an 18in option (no 17in option:( ) so I am genuinely loosing my marbles over this as I need to get new tires.
It isn't.
I mean technically it could be, but the tires would be flat.
@mountainmanjoe
They aren’t flat though. They’re 225/30/17 on ruff racing rs2 rims which are 18in only. They legit looked like 18in tires because they fit so perfectly on them, a lot of sidewall and everything looks normal which is why I was so surprised.
is the 18" rim size marked on the rim? Or is it just an opinion?
A picture might help .
I think the OP might be measuring the wheel diameter with a tape measure - which doesn't allow for the significant overlap between the tire inside diameter and the wheel outside diameter.
What YEAR and MODEL (GT, GT-S, etc.) Celica are we talking about here?
Here's what Wikipedia says about the last (7th) generation Celica:
The GT-S was powered by the 2ZZ-GE engine rated at 180 bhp (134 kW; 182 PS) at 7,600 rpm and 133 lb⋅ft (180 N⋅m) torque at 6,800 rpm. The engine featured Toyota's VVTL-i (Variable Valve Timing and Lift control with intelligence). A second stage valve lift control for intake was added to the variable intake cam phase timing. Variants of this engine were offered in the Matrix XRS, Corolla XRS and the Lotus Elise (with a Lotus ECU which added 10 bhp). Buyers had the option of a four-speed automatic with shift buttons on the steering wheel, or a six-speed manual. The base tire size was 205/55/15 but the optional size offered was 205/50/16. The tire upgrade was merely US$42 so most GT-S models had the optional wheels and tires. All GT-S models had four-wheel disc brakes and metal pedals. Manual transmission shifters and all steering wheels were upgraded to leather. Liftback cargo covers were standard along with fog lights for models without the "Action Package".
