weight difference between 295 vs 315

[95mustang_gt]

Just wondering if there is a weight difference between the 295 tires vs. 315 tires. I took my snow tires off this weekend and put my 18" saleens back on , but this year I running 315 , and last year I ran 295.To me it feels a little heavier then last year . The 315 are drags and the 295 last year were just normal street tires,if it makes a difference. Also does it put a lot of stress on the drive train running wider tires?

thanks

I have had my 315's for almost a year with no problems besides occasional rubbing, and now my tires are bald. lol
