important question about 18's on a yaris (need some help)

[ASHRAF]

Hi every body

I'm planning to buy some 18x7.5" Wheels for my hatchback Yaris

i heared that the Yaris come along with TRD 18*7.5"wheels
so I think there is no problem with the size

but what about the offset

the wheels that i wanna buy are +40

and here are some info. about the wheels

======================
4 X Incubus Black Wheels
Suit almosy all 4 & 5 Stud Cars
Size 18 X 7.5 Inch
Chrome Nuts
Chrome Valves
Offset +40
PCDs Available 4/100, 4/114, 5 x100, 5 x 114, 5 x 120
Suit Cars Such as: Lancer, Corolla, Civic, CRX, Commodore, AU, BA and much more
4 x Brand New Kumho Tyres, size to suit your car.
======================

so do they fit my car or no (without modification)

and if they do fit

what tire size do you recommend for the yaris

need some advice from you

waiting for your replies

regards,
Ashraf
