235/45R18 or 235/40R18?
 

if I had a choice i would prefer to stick to 225/45R18. however, we know that, in Singapore, this is an odd size for most tires. among reputed tires, so far, I could only find AD07 and PS1 (limited stock) for the above profile.

Given a choice, would you choose 235/45R18 or 235/40R18?

increase in ride height vs stock:
- 235/45: +4.5mm
- 235/40: -7.3mm

am thinkg of 235/45 as car is low and am worried of "humps" should the ride height is further lowered. any other things I should consider before making a decision?

also, any other tires I have missed out that carry 225/45R18 locally?

thanks in advance for any inputs.

7.3mm ?

u probably won't notice anything.

here's how it would look on 235/40R18...

that's with a set of Tanabe GF210 springs.

Hey, correct me if i'm wrong but from wat i noe, 235/45R18 is the odd size one. i've jus changed my rims n tires and i was told tat is the 'odd' 1 (cas i find 225 too narrow n 40 too thin) and 225/45R18 is the 'normal' 1, ani verification?

ok not sure abt 235/45R18 but 225/45R18 is an odd size, according to the tires I'm after.

235/40R18 no issue with most tires.

oh, i'm pretty sure 235/R45 is an odd size. as for 225/R45, since MM comes stock with tat config, i tot tat is a norm size. Cheers

The more correct size is 245/40, if you want to maintain the ride height.

Yup..... agree with Fab8...... 245/40 prolly works best....(best compromise)

yup. but understand that it may not be ideal/suitable to fit a 245 to a 8" width rim altho some manufacturers are saying it's ok to do so.

unfortunately tires like ps2, eagle f1, etc do not come in 225/45R18 for Singapore market altho they are available in the US.

Im currently running 235/40R18 front on 18x8 1/2 offset 38 and 265/35R18 rear on
18x9 1/2 offset 43 rims....
Tyres are ADVAN NEOVA AD07......
