What is OEM SI Wheel Spec?

Sorry stupid question...but what is the exact wheel specs on the SI's wheels including offset?

I'm pretty sure they're the same as the hatchback's Sport/Sport Touring wheels.

18x8 +50, 5x114.3, 64.1 mm, 29 lbs, 235/40-18 tires.

Civic Si wheels are 42700-TBF-A91 and only found on Si cars, 28lbs. and produced by Enkei.
Civic Hatchback Sport are 42700-TGG-A71, 32lbs and produced by Asahi.
Look the same though, probably same specs as you listed.

I was hearing 29 (or 28?) lbs for the Sport wheels in the sticky thread for OEM wheel specs; someone had weighed their wheel-tire combo and subtracted the spec'd weight of the tire.

Either way, they're pretty heavy for 18's. At least they look cool, though.

I took the weights from Honda's weight description for the part number, I don't know how accurate that is though.
I took off my Sport wheel with (Continental tire) and weighed it, 56lbs on a bathroom scale, obviously I don't know how accurate that is. BUT if you take Honda's weight rating (32lbs.) with Continental's weight rating (22 lbs.) you get 54lbs. Then add center cap, wheel weights, valve stem, dirt......pretty much 56lbs.

Si Goodyear tires are rated at 23-25lbs depending on the model of tire.
Si wheel is rated by Honda at 28lbs.
So Si total should be 51 to 53lbs.

Type R tire is rated at 23lbs.
Type R wheel is rated by Honda at 21.93lbs. (Magnesium alloy?)
Type R total should be 45lbs.

Is this accurate? I recall seeing a post of a Type R wheel coming in at close to 30lbs?

2017 Civic 4dr EX Turbo wheel is rated at ugly 28.79lbs.
2017 Civic 4dr Touring wheel is rated at 26.33lbs.
Firestone tire rated at 22lbs.
Continental tire rated at 21lbs. And 22lbs. for the other Continental tire.

So I'm ignorant when it comes to wheel specs. I have an 17 si. Would it fit a 18" 8.5 41mm offset rim?

Theyd fit. Little more agressive than stock. I believe our offset is around +46-48 dont quote me. I just pickes up some aodhan ls007s. 18×9 +30. Pretty aggressive. Might need fenders rolled. But I'm also stock height. Youre going up a half inch in width from stock as well. Hope I helped lol
