Tire size for 17's on TA

Tire size for 17's on TA
Been reading lots but haven't found the info I want.
Wanting to put tires on these wheels. They are 17", 9" wide. Not sure on backspacing yet but it's reasonable.
Looking for stock ride quality for a daily driver and road trip car. Think stock for 17's is 275-40-17 but I don't know if 40 series will be smooth enough. Does 275-45-17 work well here? Speedo gonna be slightly off?
Thanks a lot!

Well, 275/40/17 was in fact the stock size for SS, WS6 and Firehawk, so if you are looking for "stock" ride quality, then this would still qualify.
It's true that the 245/50/16 tires on the base V8 models (Z28/Formula/Trans Am) did provide for a smoother ride with the taller sidewall, but the trade-off is less crisp tire response (and dry traction, as they were narrower, assuming comparable tread compound.)
275/45/17 would be over 1" taller than the stock size (26.74" vs. 25.66" for the 275/40), so yes you're speedometer will be off without a retune. I'd be worried about front fitment of that height with such a wide tire and the more aggressive offset of the wheels pictured (looks like TTMs, which have a 45mm offset vs. 50mm stock). I would expect some tire scrub on the wheel well liners during hard turns.

The Eagle F1 GS-D3 - 285 / 40 / 17 fit on my Speedlines and only required an ever so slight tapping in two tiny locations on the inner wheel well with a 5 lb sledge.
Having said that, I do have an adjustable pan rod bar to center my rear end...

I would be very wary of a this 285/40 up front, especially on a 9 or 9.5" wheel that has a more aggressive offset than the stock 50mm. F1 D3 tires also tend to be more robust than other brands of the same size.
Lastly, 285/40 only increases tire height by 0.32" (little more than 1/8" per sidewall), so ride quality wouldn't be changed much either way.

Great info guys. Thanks a lot!
I wonder what the offset is of these wheels. Going to work on the car Saturday and look. Hoping I can just get a nice set of 275-40-17 tires and not have too much rubbing at the steering locks.
Posted to trade these wheels on CL for stockers, and had a lot of interested people wanting to buy straight up. But the wheels are really growing on me. I think I'm just going to get the right tires for them and see how they ride.

Well they are an American Racing Torq Thrust M wheel, so if they are 17x9" there is only one offset that AR offers off-the-shelf for this wheel; 45mm.
But with tires that narrow (215/225mm), I would suspect that they might be 17x8" versions, so best to verify that first.

Spare?
The factory spare is a space-saver unit and would not accept any of the wider stock tire sizes, nor would the designated storage area for the spare ever accommodate a 17x9" wheel and tire combo. If you wanted a full-sized spare, it would have to ride around in the trunk and take up much of the rear storage space.

I wanna see pics of the stance LOL I pulled off a couple wheels today and they are 17x9". Those Nitto 555's are getting lots of good reviews online. I might go that way. Thanks for the info

FYI, I have 275/40/17 Cooper RS3-S tires all of the way around and i'm very happy with them. They're nearly identical to Mickey Thompson Street Comps (Cooper owns M/T) only cheaper, are a good compromise between tread life and traction, and have an asymmetrical tread pattern so you can properly rotate them unlike Nitto 555's.

I've never driven anything with those tires. My friends '00 WS6 has BFG's but I think there the older Sport Comps not the Comp 2's, maybe this would be a good excuse for me to test drive his car when spring comes. I do have some pics I can share though.
First wash of the year, almost brand new wheels and tires.
Close up showing new wheel tire, and chrome vent inserts.
Fresh off the shipping pallet from the Tread Depot.
My Friend Asher standing in front of his car. He lets his dad drive it sometimes.
This is what they do if you nail it at full lock in 2nd gear at 10 mph.

AWESOME!!!
Yea these skinny tires suck. No traction and they don't ride smooth. I pulled the front wheels yesterday, they are 17x9' with 45mm offset. Gonna get new tires soon. Will look into those rs3-s. Hoping I can get $100 for these tires after I pull em off. Decent meat on there.

Thanks for the pictures, I wanted to see how the 275 Coopers fit a 9" wheel since some brands run a bit narrower than others and I haven't yet seen the RS3-S in person. Looks like they are a great fit. I don't need new ones just yet, but in planning ahead it will either be these RS3-S or the BFG Sport Comp 2.
