whats the biggest tire i could safely fit on it? i dont want to be stretching but i dont want to be bulging out the sides either i was thinking a 225/45 would fit nicely whats your thoughts?

thanks, phill

 

a 235 will fit nicely phill

 

AWESOME! they would be sweet. more grip than my car can hande lol..........untill......my TURBO! YES!!!!

 

235's look a bit chubby on a 7.5" rim. 225/45's are perfect IMO. I'm actually considering the black MSR 090
17x7.5's. I will get 225/45's. They are only 1/10" smaller than 225/40/18 tires. 235's also add 2-3lbs over 225's, so acceleration will be better with the slightly smaller in diameter and lighter 225's. The only way I would go to 235's is if you have a lot of power upgrades. Then you may actually benefit from the wider treads.

Here are some pics of 235/45/17 tires on 17x7.5 rims.

alright cool and there cheaper so sounds like a good idea to me

 

There are more in his gallery.

 

yea thats what im looking at now. mannn i though 235's would be so much wider. and 225's are gonna be even more thin. dam.

 

how wide are the stock ss/sc 18's?

 

i guess another question is all season or summer dedicated? i have steeleis to put on for winter but idk if i should go that way. MD winters arent that intense

 

rims are 7 tires are 215

 

SS/SC rims are 7 inches wide. SS/TC rims are 7.5 inches wide

 

my bad, fixed lol

 

Get summer performance tires. All seasons suck for traction. Pick a tire with a tread wear rating below 300. I like the Nitto Invo 225/45'/17's. You can get a better quality 17" tire for the same price as a crappy 18" tire. That's what is attracting me to 17's right now! lol

 

yea but im not gonna wanna put my steelies back on lol.

 

See above! lol

 

yea i saw lol.

 

go with a dedicated summer tire. you will be much happier

 

good to know. ill def go with a summer dedicated.

what you guys think about these tires. there 235's but there cheap as hell and get good reviews.

and you better take them off for winter! dont pull another one of your "incidents" lol

 

rofl! yea. i guess thats enough reason to get winter tires in its self.

ony one on these tires?

Those will be REALLY sticky, but a wear rating of 160 means they won't last long. Try and stay between 200-300.

 

what are yalls opinions on 245 width tires on the stock 18's?

 

thats pretty wide man. i am putting 245's on 8.5" inch wheels. 225/40's look perfect on the stock SS/Sc rim in my opinion, so in a 7.5" inch a 225 or 235 would look great.
