Wheels & Tires - Quik Wheels Advice Question

Well evidently i have 18x10's all the way around with 275/40/18's on them, i bought the wheels and tires used. Well I was looking at getting some Firehawk Wide Ovals and they only come in either 295's or 245's, well i know 245's will be too small, you guys think it would be a problem running 295's all the way around?

we have 295s on our stock 18x10 GM wheels. They actually run pretty narrow. I'd like to see a 305 or a 315 in that tire but they don't make it. :(

295's should fit just fine.
