i was gonna go with 245/45/16 but i figure they would rub on gt models because of the fenderwells & stuff. so im going to go with the draglite rims their 15x7 whats the most common size for them? i was looking 245/50/15 but no luck so whats the common size for them?

You know, I've heard that 91+ can run 245's on the front with no rubbing issues, not sure about this though. If worse comes to worse, roll the fenders, I'll probably end up doing it, and it can't cost THAT much, right?

245/50/16 will fit on a gt...

and most go with 15X8 rims in the rear their are some threads here with the backspacing listed and tire size some run 265/50/15. just do a search and you should come up with some results. or maybe someone who knows off the top of their head can chime in..

i was gonna get 16x7 and put 245/45/16s on but ive heard from alot of people itll rub on my 88 gt. not sure how true it is. so i think ill end up going with 15" rims.

I think 255(or 265)/35/17 or 18 mounted out back with some 245/35/17's in front would look sick

245/50/16 shouldnt rub with a 16X7 ive seen them on a fox gt stang with no issues at all.

most stangs run wider tires than that...

ya hopefully they wont. i know i have 225/60/16 on there now and they rub. thats why i asked about the 245/45/16

I have 225/50/16 on mine and theres plenty of room for a bigger tire... i bolted on a set of 15x8 welds with 255/50/15 drag radials on and they didnt even begin to rub at all. and i had steeda lowering springs on it at the time....

245/50/16 will not rub unless something is off on the car..



something to remember when selecting a tire is the first number (245) is the measurement from rim up the side wall across the tire and down the other sidewall to start of rim. the second number (50 or 45 and so on) is a percentage of the first number to tell you how much of the first number is the sidewall.

For example if the first number is 245 and the second is 50 then the sidewall is 50% of the first number so if you decrease the second number and keep the first the same you are going to make the sidewall shorter and tire wider and if you raise the second number and leave the first number alone you will make the sidewall taller and tire narrower.

if you change the first number up and leave the percentage the same the tire will get taller and wider and if you bring the first number down and leave the percentage the same you will make the tire shorter and narrower.. thats how when you alter either number it effects the height and width of the tire. alot of people dont understand this when selecting a tire.


here is a link to a tire size calculator where you can put in the size you have and the new size you want and it will overlay the new tire size over the old tires outline to show you how much bigger or smaller the new tire will be over the old. it gives you a view to see how tall or short it will be and a side view to show you the width. hope this helps.

you can play with the combinations to get the same height but wider tire or vise versa it takes the guess work out of selecting a tire size you want....



i know it says miata tire calculator but you can put in any tire rim size on there and it will show you the difference i came across this awhile back and found it very helpful
