why so high at 40? 32ish is fine as when warm it'll be around 35 hot.

 

Looking good!

Uh no. its 35ish. dont give false information. if your not sure dont post.

 

loving the setup man!! looks great!! specs?

 

i got a set of 17x8.5 +20 ... the tires that are on it are same as stock i believe.. 205 40 17 and 225 40 17.... with camber should this fit? anyone running something similar?

Edit.. forgot to mention that i have a basic fender roll already

I have 17x8.5 at+15 had to do a little more of fender roll to fit, but got away with the stock camber when i lowered the car. 205-45-r17 tire.

I don't give false info to anybody, I will school you with tire profiles/air conversions/ride heights with profile ratios, percentages/load capacity if it does or does not exceed manufacture specs. Im certified through RMA, TIA, Michelin, bridgestone, bf goodrich for 8 years now,so don't come in here thinking you know more, I know my stuff!!!

A 215-35 on a 18x9.5 is a 2.78 inch stretch which will shrink the height of the profile, lower the weight ratio capacity, inccrease the temperature rating of the tire and also lower the car about .5, so total height of the ground can be 24-27 inches of the ground depending on brand and tread wear of tire, in order for the tire not to overheat and cause an explosion when driving high speeds or high temps, the tire needs to have an extra load capacity of at least 87 or above and a speed rating to be a w or z also depends on the brand. The weight of an 04-09 s2000 is 1565 for the front and 1850 for the rears will adds up to 3,600 with half tank of gas and average weight of one occupant of 150,that being said the tire air pressure at 35psi with a tire of 215-35 with losing 2.78 of the sidewalls can hold a weight of 1126pds max per fronts!!! 40 psi would be at 1594pds with any temperature up to 100 degrees outside will be more than plenty for the weight capacity of the tire at any given speed available for the fronts, rears would have to be at 46psi. Stock sizes on 32 psi proper fitment factory tires with no stretch and with a z-rated speed rating holds it 1582 for the front, and rears are wider with higher capacity and temperature rating and holds up to 1935 which is more than enough.

Also having high pressures will increase better wear if u run excessive camber, and are an aggressive driver. This also ensures the bead will hold up on the wheels and sidewalls. Which stretch tires losses the bead seal every once in a while.....

So your for sure 35ish psi with 1126pds on a 215-35-18 with 18x9.5 FAILS!!!!!!! buddy
