I have a quick question. What's the best tire size recommendation you'd go with?

So far I'm seeing people do 245/35/20 front and 275/30/20 rear. Is that the only size that can be done with this car that won't drive VDC nuts and also provide some kind of comfort with the 20" wheels?

 

245/30/20 and 275/30/20 or 255//30/20 and 285/30/20 are the correct sizes for 20's. Some people run 35 series because they are scared of potholes etc, but IMO it makes the fronts look goofy and taller than the rear

 

Thanks Redlude for the quick reply. Although For some reason or another, at a quick glance I thought the last mod you have listed said hotchicks lol

Thanks bro for this link this place is about an hours drive.. hell with the order i can have them put on right then

 

Thanks guys! See this is why I love this forum so much

 

Here's a link if you're really technical. compares the front and rear of stock 19's:

Man...thanks! This helps a millionfold. Izmir, did you use this site when you were shopping for wheels?

 

I run a 245/35 and 275/30 on my sedan. If I had a coupe I would go wider.

 

Ttrank how wide would you go?

 

Yes i did. I also contacted the vendors on here to gather all my info. they were very helpful. i used the search function too and found all the info i needed by posting in old threads.

 

Thanks guys I'll have to keep that in mind knowing when I should begin budgeting for new tires etc.

Ok...here's a quick situation I'd like to share about some 20" wheels. I've been asking around regarding wheel weights on some 20" Axis MODs and have gotten mixed responses from different people regarding them.

I took a nice amount of time this morning and researched some tire selections that fit this wheel and with the help of a few awesome people on this board and on driver I've learned that these can use 245/35/20 and 275/30/20 just fine.

According to Axis the rims weigh 26.1 front/28.1 rear. If the stock 18s are 24 F and 26 R that would result in a 2.1lb gain in mass per wheel in both the front and rear wheels. (No tires of course)When it came to tires though, I discovered that not all tires weigh the same. The stock 18 Mich. tires run about 24lbs F and 26lbs R and when checking the different brands available in that size range, I found some that weigh between 5-6
lbs more than those.

So I started feverishly checking out different tire packages to see if I could crack down on a set that would equal a weight as close to stock as possible. After checking out various sites including tirerack.com, I found out that the General Exclaim UHP not only got the
highest remarks but also weighed in at 25 lbs for the Fronts (click on specs) making the combined total weight as 51.1 lbs ( 3.1lbs heavier than stock)

They didn't list a tire to match the 275/30/20 rear size for this brand, but the Kumho Ecsta SPTs

http://www.tirerack.com/tires/Compar...0&startIndex=0

came in at about 30lbs (again click on specs) which would make the combined total weight = 58.1 lbs or 6.1 lbs heavier than stock.

So what I'm saying is that while 20s this side of the widely praised Volks, Iforged etc. usually weigh more and significantly slow down acceleration performance and increase braking dist over stock, managing combined wheel weight of tires and wheels could possibly help reduce those seemingly negative effects. For me, this was an important ordeal bc I'm considering the Axis MOD wheels in this combination bc I like the design and wanted something I can be comfortable with. I do care about ride performance and gas mileage.

From the responses I've heard from a few folks, some say yes performance goes down some say no it doesn't. Which leads me to think it may be the result of different overall combined weight gains with the variations of people's tire choices etc.

Personally, I believe I may have found some kind of solution that can help those looking for 20s on a budget right now. Check the weights for these wheels AND the weights for the tires too.

The real question is, how much more can 3.1 lb increase in weight per each front wheel and 6.1 lb increase in weight per real wheel, in a 2" increase in diameter effect the vehicle's overall ride and drive, acceleration and braking abilities? Keep in mind this is considering the car is stock.

Is it a big noticeable difference for daily driving lightweight stop and go/mild highway? Or will the car struggle to drive like we're rolling with 3 400lb sumos in the back?

I guess this would be a question aimed at those who own similar wheels and know the combined weight gain/or loss! Come on wheel experts I'm counting on you! Please help me out

go w/ a 245/30 and 275/30 Toyo makes this size

 

You also have to consider how the weight is distributed on the rotating assembly. The further out the weight is to the OD (assuming they are all the same for speedometer accuracy), the more power it will take to start rotating the wheel/tire assembly. The car will theoretically accelerate slower as you go up in wheel diameter. Will you feel it? Maybe, or maybe not; but aren't + size wheels for the bling? If so will it really matter much?

IMO, unless you are autocrossing, go with what looks good to you.

BTW ... you can easily chop more rotating mass by going to a BBK!

 

safe to do 285s on a 10" wide rim?
