Ok Right now my rims and tires are as follows:

Front:
Rim: 19 x 8.5
Tire: 245/35-19

Rear:
Rim: 19 x 9.5
Tire: 275/30-19

Right now it is rubbing every so often in the back even with the fender rolled. I dont wanna chance the camber up since it is a daily driver for the wife so...

Question is: Will it hurt to change the Rear Tires to around 245/30-19 without changing the front tires at all? Was told if I go to that tire it wont rub, but dont know if it will adverse effect the front tire. OR maybe move the front tires to the rear and change out to new front size? I have no clue!!! Any advice on another size to run with in the rear that will avoid rubbing or what I should do all around would be greatful. More a speed guy that i tire guy.

245-30's will cause tire dia differences with the 35 series tires on the front.

What is the rear offset..that's the real problem

I have no clue but they have like a 3" Lip on them!

if you dont have a clue about the offset, well you dont have a clue..

you might do some research...

you are asking, i like blue, is that wrong?

That is one of the main reasons why I am asking. I have no clue on finding offsets on the wheels or where to start.

I guess telling me to do research is like telling a new guy on here who has no clue about the search function to us it. People just expect others to know it all in the first place.

Thanks for your obvious sarcastic post, but posts like these arnt needed when others actually need legit help and might not know the first step to take....

If you change the tires to 245 - make sure they are 245/35 same as the front.

You will lose some under steer and get back to the stock like handling of the 8. Remember, the car came with same sized tires on the front and rear from Mazda so that is the way is it supposed to be.

245 will be ok on a 9.5 rim - but if the offset is low (+28 is LOW / +50 is Factory) then you may still rub - go read the stickers on the wheel; they should tell you the offset.

Usually the offset is cast into the backside of the wheel somewhere...if you pull it off..you can probably find it.

I would guess they are about 32-35 if they are rubbing...common sizes for other applications

You have to decide what you want to do....continue to try and get wrong sized wheels to fit..by rolling fenders/missmatching tires....or buck up and buy the correct wheels to fit in the first place.

Knowledge is power....the idiot that told you they would fit in the first place is the one who started this...and you didn't do your research before you bought them...

Offset is the distance from the hub (where it bolts to the car) to the inside lip of the wheel.

So you can see how the bigger the number is the less will be sticking out giving you the big lip look you have now.

Well, each tire is different and each wheel is different. I guess some vendors and salespeople will make you believe that you can just find a wheel you like and slap it on your car and all will be fine, but cars are pretty picky on what sizes they can accept.

Sorry to say it, but it looks like your going to have to sell those wheels and go for the same type in 18", or stay with the 19" wheel with a bigger offset, or buy some coil overs and raise the car an inch or so.

Either way there's really not a quick cheap fix for this problem.

a search for offset would have yielded this..

Thanks a ton for the info. Noiw I can look into what imma need to do. I bought these off a guy on here who had them on his and they never rubbed on his. I finally got ahold of him and he told me his camber was adjusted in the rear to allow them not to rub. Ill see what I can do.

Just one question: Would the 245/35 in the back to match the front be ok even though the rim is wider in the rear?
