6x9 +15 tire question

[shalezzz]

hi, just bought those 16x9 +15 square wheels that enjuku racing was selling since it was a decent deal and i wanted to have something a little lighter than my rota p45rs for my 90 hatch, they recommend a tire size of " 205/45/16 on front and 225/45/16 in the rear." i trust enjuku but is that right cause dont most (of the few people who run 16's) run a 50 sidewall thickness it seems like that would be much smaller than stock. and if you look at this link ( http://www.enjukuracing.com/images/g6front.jpg ) theres alota wheel gap. but i dont know if it just looks small because of the aero, btw any input would be greatly apperciated. and my fenders are rolled with megan track coils that are maxed out and just bought some rucas if i need increase my rear camber, and i cant pull to fit large tires because of some quarter rust... im more worried about the fronts than the rears. thank you for any help
based off what i heard from nico im thinking either 225/45 or 235/45 all around??

Okay factory rims were 15" and they came 195/60/15. When you break down the tire number, the middle part(sidewall) is just the percent of the tire width. your running 16x9. so lets say you run 225/45 is 45%of 225 greater than 60%of 195. using this for any possible tire size should help, and take into consideration the 1" difference in the factory wheels and the wheels you just got

hope this helped

Use this, but also keep in mind that sizes can vary slightly from brand to brand, so check for detailed dimensions on the tire manufacturers website if you want to be absolutely certain.
