2003 Mustang GT - Rear Tire Size Question
- Thread starter Cassiebaebae
- Start date
Tyy sm… Is there any numbers besides that? I want it to fill up the wheel wells it looks dumb
gkomo
now i can hopefully expect to receive the shaft
Fill up the wheel well in what way? width or height? as mentioned 315's will satisfy the width requirement, but if the car isn't lowered there will always be a gap between the tire and fender. Is the car lowered at all?
No the tires on it now look small they are 275/40r17s what would make them taller sorry for dumb questions lol new to all this ty! So 315 what? i know the rims are 17’s

315/35 17 should be what you are looking for. 25.7 height which is right at factory and same as those 275/40.
HOWEVER - if you want a taller tire to actually fill out a non lowered wheel well you'll have to measure etc and find the appropriate sidewall height etc. Usually lowering a car is the best solution etc.
What is front tire size and are you trying to match that height? (FWIW, a 275 on that 10.5 wheel probably looks super stretched).

I will look and let ya know. Yessss the back tires look crazy! Can you point me in what i need to buy to lower i will post pictures of it when I get home. Ty!
Don't change your tire height. 
The speedo will be off and you would be sacrificing torque for a top end you will never use.

Lowering springs vs coil overs. HUGE debate there. Lowering springs are cheap and the avg joe can install fairly easily with a jack and some basic hand tools. Coil overs go a bit further with needing specific shocks/struts and similar hand tools etc.
I am an Eibach Sportline fan - I like the car low. That being said my rear springs are now eibach drag launch, but car is still slammed with steeda weight jacker Lower control arms. Fronts are still Sportline but will get replaced with winter with coil overs to complete the drag suspension setup. I might even go rear coil overs this winter as well and go with a straight non coil perch LCA so I can get my freaking sway bar alignment back to somewhat normal. Who knows on how deep my check book goes this winter with everything else.
You can litterally take your pick of specific or progressive rate springs in .5-2.5 drop ranges.
Show pics of the car and list your goals. Street cruiser or drag or road race or somewhere in between?
Ok, Idk what the factory tire size is someone painted over the sticker that shows all that infoDon't change your tire height.

The front tires are 245/45zR17. Here is a picture of it from the side can you see the gaps it looks crazy

That would be all the tires right? Cause someone put 17x10.5’s on the back. Sorry im trying to learn about this

100% lower it. Springs of your choosing (at least a 1.5 drop IMHO) and some good caster camber plates- Maximum motorsports 4 bolt - buy once cry once.
If you want a tad lower and don't mind a slight creak once in a while, lower without isolators to get another 3/8-1/2 inch.
I wonder if it has drag springs or something on it, that seems like it sits high even for factory - but I've not had a factory height car since 2004 lol.

Yessss it looks so weird i def. want it lower. I dont know much about all this but been trying to get my friend to help me figure it out. I seen some 2” springs is that to much?

Depends on how rough your roads are and how much attention you pay. If careful and not trying to off road 2 inch is perfectly fine and will make it look a ton better.
Depending on miles you may look at ball joints and other wear items as lowering will speed up failure on prior worn parts. But don't skip the caster camber plates.
