Hi Guys, Anyone here is on a 17" wheel setup? same all round or staggered? I am trying to make a choice between 17" or 18" and I'm on Malaysian roads alot where there is a lot of pot holes. Will 18" tyres be too thin such that will damage the rims when kena pot holes?

Or should i stick to my current 16" wheels?

csl

It is not the tyres thin but bigger diameter = weaker rim. I have both 17" and 18" on different cars. 17" still survive until today. But the 18" got 1 pc already bent.

End of the day, it will still depends on the driving behavior. 15" will not survive on a berserker's right feet.

nope i am a normal driver not a mad man so assuming this the 17 inch will survive the pot holes more than the 18 inch assuming both forged rims.

Dont use forge rim if you want long lasting rim.......

Lennon, you meant forge rim is only for lighter but not stronger or lasting... interesting, I thought of getting the forge rim...

coupe07

forged rims are light and very strong wat....

nex100

from what i know it is supposed to be light and strong. Looks like all the rx8 in sg all use 18 inch no one uses 17 inch wheels

(+) Forging uses intense heat and/or pressure to transform a solid slug of alloy material into the final shape of a wheel. Forged wheels are typically lighter and stronger than their cast counterparts.

(-) Forged wheels are more expensive due to the cost of the manufacturing and machining processes

nex100,
18s" are stock setup for the MTs. i do see some 17s" around thou.

imho: choose 1 good one, 1 you like... wear it, like it, play safe with it

Yes, that's what I know too... and did some research on forged rim from Wheel Tech:

FORGED OR SEMI-SOLID FORGED

In forged wheels, computer numerically controlled (CNC) mills add the cosmetics and the bolt circle to exacting tolerances.
The ultimate in one-piece wheels. Forging is the process of forcing a solid billet of aluminum between the forging dies under an extreme amount of pressure. This creates a finished product that is very dense, very strong and therefore can be very light. The costs of tooling, development, equipment, etc., make this type of wheel very exclusive and usually demand a high price in the aftermarket.

17" pickup faster than 18" :D

I dunno whether it's because of the manufacturing quality or wat..... My 3 year old BBS is in better shape than 3 month old Mazdaspeed rim (well that was checked 2 years ago)......

i use 17x8. much lighter combo than the stock rims. i run an undertired setup too. 225/45/17 front and 245/40/17 rear on michelin pilot sports2. pick up and handling is better than my stock rim with AD07. maybe its the tires.

My 17x9 with 245/45 ride much nicer than the 18x9.5 with 275/35. I esp notice it as I have coilovers. With the 18s I keep the tire pressure down to improve the ride, but if I was to hit a good sized pothole...maybe low pressure is not so good (I haven't). I also think the 17 accelerate faster but the steering response is a tad slower.

Stephy88

size does matter... in 1 way or another
really is wat you want...

looks vs comfy vs weight vs cost etc...

nex100

What kind of rims are you using? How much is the weight?

I don't quite get it when you say steering respose is slower. You mean bigger rims give better steering response? Now I am using 16 inch so my steering response when i switch to 17 inch will be better than now?
